THERMAL SPRAY COATING

PROCESS

Thermal spray coating involves the use of a torch to heat a material, in powder, rod or wire form, to a molten state and the use of a gas or air to propel the material to the target substrate, creating a completely new surface. The coating material may be metal, alloys, ceramics or carbides with unique physical properties that are, in most cases achievable through the thermal spray process.

Thermal spray coatings are a highly cost-effective and straightforward method for adding superior properties and performance qualities to a given engineering surface. In this method, we can deposit any metal on any metal. Even certain metals can be deposited on plastic, wood, and even paper. In certain cases the temperature of part can be less than 100-degree centigrade so there is absolutely no distortion on your parts.

PURE METAL AND ALLOY

Pure Metal-Alloy coating gives the desire properties of pure & alloy metals on the targeted component. Types of material for coating include Aluminum, Zinc, Copper, Nickel, Molybdenum, Tin, High Carbon Steel, Medium Carbon Steel, Low Carbon Steel, EN-8, EN-9, EN-31, Nickel-Chrome, Nickel-Aluminum, S.S.304, S.S.316, S.S.316L., S.S.410, S.S.420, S.S.430, Monel, Brass, Babbitt, Tin Bronze, Phosphorus Bronze, Aluminum Bronze, White metal, Inconel

CARBIDE COATING

Carbide coatings give ultimate wear resistance properties to abrasion, erosion, galling, and fretting. Most carbide coatings are applied by HVOF to achieve the densest and most well-bonded coatings available by thermal spray. Types of Carbide coatings include Tungsten Carbide, Chrome Carbide

SELF-FLUXING

"SPRAY & FUSE” COATING

Spray and Fuse coating gives a metallurgical bond for high bonding strength along with hardness. They are also more resistant to chipping than the other coating processes. Due to the higher percentage of Cobalt or Nickel, they will not rust.

CERAMIC COATING

Ceramics coating gives tremendous hardness, enhances surface properties, and abrasions resistance coatings. They are most often applied using plasma spray due to their high melting temperatures. It is mainly used in textiles parts and pump shafts, sleeve, piston, and plungers. Types of Ceramic coatings include Aluminum Oxide, Chrome Oxide, Titanium Dioxide, and Zirconium Oxide.

HARD FACING ALLOY COATING

Hard Facing alloy coating gives high hardness properties. A hard, wear-resistant material is deposited onto the substrate to form a coating. It is applied to reduce wear or loss of material by abrasion, impact, erosion, galling, or cavitation.
