PRODUCTS

1. AlCrN (Aluminum Chromium Nitride) Coating

Before Coating: Raw, untreated surface; cover edges present visible residual adhesive or mechanical scratches.
After Coating: Cleaned surface; AlCrN coating exhibits uniform adhesion; smooth and flat edges with zero visual defects.
Technical Features: Excellent high-temperature oxidation resistance (up to 900–1000°C); significantly enhanced surface hardness and wear resistance.
Application Benefits: Perfect surface defect remediation; superior substrate protection under extreme environments; maximized component service life.

2. DLC (Diamond-Like Carbon) Coating

Before Coating: Substrate retains original silver metallic color; low scratch and wear resistance.
After Coating: Uniform bright black surface finish; enhanced aesthetics enabled by ultra-fine carbon nanostructure.
Technical Features: Exceptional surface hardness enhancement; minimized coefficient of friction (CoF) with self-lubricating properties.
Application Benefits: High wear resistance; anti-sticking/anti-galling properties; physicochemical corrosion resistance; maximized component service life.

3. TiN (Titanium Nitride) Coating

Before Coating: Substrate retains original silver-grey metallic color; untreated surface with low scratch and wear resistance.
After Coating: Uniform, bright gold (metallic yellow) surface finish; significantly enhanced aesthetic appearance and premium quality.
Technical Features: High surface hardness enhancement; reduced coefficient of friction (CoF); excellent thermal stability and heat resistance.
Application Benefits: Superior mechanical wear resistance; effective prevention against surface scratching; significantly extended component service life.
