Spray Galvanizing Services

Spray Galvanizing Services Atomized particles of molten Zinc are projected on to abrasive blasted steel surface from a special flame or arc pistol fed with Zinc wire. The process is often applied to structural components too large to be dipped in a galvanizing bath and to structures which are likely to distort during hot dip galvanizing. Zinc coatings for iron and steel provide excellent corrosion resistance in most atmospheres and in contact with many natural and synthetic substances. Zinc coatings are widely used to protect finished products ranging from structural steel work for Chemical, Fertilizer, Refinery, Cement, Power Plant, Buildings, Bridges, Pipelines, etc. The electrochemical relationship between zinc and steel enables zinc coatings also to protect steel at cut edges and at breaks in the coating by a sacrificial action. Applications : All steel structures Transformer tanks Radiators Dairy Coils Communication towers Steel Tanks Wind Mill Towers Electric Poles Gates Windows Building Structures Gutters in chemical-related industries Advantages : Proven long-term protection Cold process No size limitations Ideal surface for painting Site-jobs possible No hydrogen embrittlement Preferred even under alkaline condition

Chimney Coating Services

Thermal Spray coating of Aluminium involves deposition of Aluminium of 99.5% purity over the prepared abrasive blasted surface. The sprayed metal is melted by using electric arc that is atomized with compressed air and projected over the substrate. According to the IS & BS Standards, the coating should be resistant up to 950 C temperature. The Aluminizing process is used to protect parts operating in high temperature environments against corrosion and oxidation. As a result, the most common parts coated are high temperature industrial chimney and muffler. Advantages of Aluminizing on Chimneys: • Aluminizing will with stand temperature upto 950 deg. Centigrade. • Aluminizing will with stand at elevated temperature (Due to elevated temperature there is a possibility of Painting can fail by performance (peel off). • Minimum expected life of Aluminizing will be 10 years & above in any Environmental conditions. • We have carried out Aluminizing on more than 100 chimneys for various companies across India. • We will give 10 years Warranty from the date of completion of work for the performance of Aluminizing.

Bridge Coating Services

Bridge Metallizing Services All metals have properties that cause them to react as an anode or a cathode when coupled to another material in a corrosive environment. The application of zinc (anodic coating) to iron substrates forms a protective layer and results in corrosion protection referred to as cathodic protection or sacrificial protection. Aluminizing or Spray Galvanizing provides good mechanical interlocking based on quality abrasive blasted pre-treament. Coating thickness of up to 500 microns can be applied though the industry standard is 100-150 microns. Aluminizing process is ideal in high temperature environments to prevent oxidation and corrosion. Coating with sealants provides a base for paints for longer life to structures.

Zinc Spray Coating Services

The zinc spray galvanizing process starts with the preparation of the Structure’s surface by removing rust, unwanted surface coatings, oil and other contaminants. The cleaning is done using high-pressure abrasive blasting, which also roughens the surface. This increases the surface area and ensures a successful adherence of the zinc coating. The atomized metal particles are then sprayed onto the roughened surface where they attach to the surface and solidify. Several layers are applied so as to build up the coating thickness, with typical values ranging between 80 microns and 300 microns, but thicknesses of 50 to 500 microns are also possible. Zinc coatings widely used for the protection of finished objects are made from mild, low-alloy and high-carbon steels. The excellent corrosion protection is effective in most atmospheric conditions and also when the product comes into contact with either natural or synthetic corrosive substances. Protection against aggressive environments such as salt spray conditions can be enhanced by applying one or two epoxy paint coats onto the zinc coating. Zinc spray galvanizing is commonly used on structural steelwork for: Windmill towers Chemical, cement and fertilizer industries Refineries Power plants Pipelines Bridges and other marine applications Transformer tanks Radiators Other advantages of using zinc spray galvanizing include: Cold process Suitable for all sizes Surface is ideal for painting No hydrogen embrittlement Suitable for alkaline conditions Jobs can be done on-site Long-term protection Variable coating thickness

Flame Spray Aluminum Coating Services

Flame Spray Coating Services Flame spraying is a thermal spray coating process that produces high quality surface coatings using heat, from the combustion of a fuel gas with oxygen, to melt a spray coating material which is propelled onto a substrate. Flame spraying offers a cost effective alternative for applying metallic and ceramic coatings in a less demanding environment. The utilization of the flame spraying surface treatment allows the spraying of a wide variety of metallic or ceramic coatings on to a large range of component materials where good wear resistance and excellent impact resistance are required. As the surface technology specialists in flame spraying, Bodycote provides an array of thermal spray coating materials to suit your specific needs. Backed by a customer-driven service, our facilities process a wide variety of component sizes to exacting standards with reliable, repeatable results. Benefits There are particular reasons why flame spraying may be used: Component geometry or the working environment requires manual thermal spraying, offering the easiest working conditions; Large & complex areas (structures); The required thermal spray coating performance is achieved with flame spraying; and Cost effective Application & materials : Flame spraying is widely used where a cost effective thermal spray coating is desired and a lower quality can be tolerated. The majority of components are sprayed manually. Corrosion protection; structures and components Reclamation worn shafts, particularly of bearing areas with materials such as stainless steel or bronze alloys The surface coatings produced are porous and lubricants can be absorbed into the coating, enhancing performance of the bearing. Aluminium, zinc, stainless steel, bronze, low carbon steel, nickel-based materials, molybdenum. Process details : Flame spraying uses the heat from the combustion of a fuel gas, usually acetylene or propane with oxygen, to melt the spray coating material. In this process a consumable, usually a powder or wire, is heated and propelled onto a substrate to form a surface coating.

TSA Coating Service

TSA Coating Service Thermal sprayed aluminium (TSA) coatings are widely specified for the protection of steels from aqueous corrosion, including offshore structures and components that are exposed to seawater immersion, tidal and splash zone environments. In this paper, the performance of TSA coatings prepared by conventional and newer wire thermal spray systems is presented. The TSA coatings were characterized in terms of deposition efficiency, coating micro structure including porosity and oxide content, surface roughness and coating adhesion. A cost analysis for coating deposition using the various systems is included. The corrosion behavior of the coatings was compared using an accelerated electrochemical corrosion test method. In addition, longer-term free immersion tests of up to 31 days were conducted in 3.5wt% NaCl solution, pH 7.9-8.2, 22-25°C. The TSA coating performance was quantified in terms of its free corrosion potential and the corrosion rate which was estimated from linear polarization resistance (LPR) measurements. The ability of the TSA coatings to provide adequate cathodic protection to exposed bare steel in immersed saline environment has been demonstrated. The newer systems have been shown to produce TSA coatings of improved quality and the effect of this on longer-term corrosion protection of steel substrates in immersed saline environment is discussed. Thermal Spray coating of Aluminium involves deposition of Aluminium of 99.5% purity over the prepared abrasive blasted surface. The sprayed metal is melted by using electric arc that is atomized with compressed air and projected over the substrate. According to the IS & BS Standards, the coating should be resistant up to 950 C temperature.
