Tungsten coated sleeves are high-performance mechanical components—often made of stainless steel or alloy coated with tungsten carbide via thermal spraying—designed for extreme wear, abrasion, and corrosion resistance. They are crucial for protecting shafts and seals in high-pressure, high-temperature, and corrosive industrial environments.

Aluminium coating services apply durable, decorative finishes to aluminum parts, primarily using powder coating (electrostatic application of dry powder, then cured with heat) or thermal spray (TSA) for protection against corrosion, wear, and fading in industrial, architectural, or consumer goods, enhancing beauty and extending lifespan with various colors and textures. These services involve careful surface preparation, precise powder application, oven curing for a hard finish, and cooling, ensuring strong adhesion and compliance with quality standards like Qualicoat. 

Zinc flake coating is a high-performance, non-electrolytic coating system using zinc and aluminum flakes in a binder, creating a thin, durable, and aesthetically pleasing layer that offers superior corrosion resistance, especially for fasteners and automotive parts, without causing hydrogen embrittlement. Applied like paint and cured, it provides sacrificial protection, prevents galvanic corrosion, and can be enhanced with a topcoat for specific properties like lubrication or color. 

Zinc spray coating services apply a durable, protective layer of zinc onto metal surfaces (like steel/iron) using thermal spray techniques (e.g., arc spray) to provide superior, long-lasting corrosion, rust, and wear resistance, extending the life of structures, industrial equipment, and automotive parts, especially where hot-dip galvanizing is impractical. These services offer a sacrificial coating, forming a tough barrier against harsh environments, and are ideal for infrastructure, marine, and industrial applications, often involving grit blasting for preparation and offering benefits like weldability and paintability. 

Metal spray coating (or thermal spraying/metallizing) applies molten or heated metal onto a surface using high-velocity gas, creating a durable coating that enhances corrosion, wear, and heat resistance, extends component life, or alters surface properties like conductivity, without melting the base material. It uses wire or powder feedstock, melted by electric arc or flame, and atomized onto a prepared substrate for a hard, bonded layer, offering robust protection for various industries.
