Quality & Testing

Chrome plating, also known as chromium plating, is a surface finishing technique used to apply a thin layer of chromium onto a metallic spares & parts.

Chrome plating, also known as chromium plating, is a surface finishing technique used to apply a thin layer of chromium onto a metallic spares & parts. 

1. Surface Preparation:

   - The surface of the metal to be plated is cleaned thoroughly to remove any dirt, grease, or other contaminants.

   - If necessary, the surface may be polished or buffed to remove surface imperfections.

 2. Acid Cleaning:

   - The metal surface is etched in an acid bath to remove any oxides and to promote adhesion of the chrome layer.

 3. Electroplating:

   - The metal part is submerged in an electrolyte solution containing chromium ions.

   - A direct current is applied, causing the chromium ions to deposit onto the surface of the metal part, forming a thin layer of chromium.

 4. Post-Treatment:

   - After plating, the part may undergo additional treatments to improve its corrosion resistance, appearance, or hardness.

   - Passivation may be performed to further enhance corrosion resistance.

 5. Final Inspection:

   - The plated part is inspected to ensure that the chrome layer is uniform, free of defects, and meets the required specifications.

Benefits of Chrome Plating:

-  Corrosion Resistance:  Chrome plating provides excellent corrosion resistance, protecting the underlying metal from rust and degradation.

-  Hardness:  The chromium layer is extremely hard, providing wear resistance and durability.

-  Aesthetic Appeal:  Chrome plating gives metal parts a shiny, reflective surface that is aesthetically pleasing.

-  Easy to Clean:  The smooth, non-porous surface of chrome-plated parts is easy to clean and maintain.

CrN Coating

CrN Coating, also known as Chromium Nitride Coating, is a thin film coating applied to steel and other materials to improve their surface properties.

 Composition: Chromium Nitride (CrN) coating is composed of chromium and nitrogen. It is deposited onto the substrate using Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD) techniques.

 Properties:

-  Hardness: CrN coating is extremely hard, with a hardness of around 2000-2500 HV (Vickers Hardness).

-  Wear Resistance: It provides excellent wear resistance, reducing friction and extending the lifespan of the coated component.

-  Corrosion Resistance: CrN coating offers good corrosion resistance, protecting the substrate from oxidation and chemical degradation.

-  High Temperature Stability: It maintains its properties at high temperatures, making it suitable for high-temperature applications.

 Applications:

-  Cutting Tools: CrN-coated cutting tools have excellent wear resistance and can withstand high-temperature cutting operations.

-  Mould s and Dies: CrN coating is used to protect Mould s and dies from wear and corrosion, prolonging their lifespan and improving productivity.

-  Machine Components: It is applied to various machine components to reduce friction, prevent galling, and improve overall performance.

Overall, CrN coating is a versatile surface treatment that improves the performance and lifespan of steel and other materials in various industrial applications.
