ALUMIUM COATING TECHNOLOGY A-COAT

Description:
Our A-Coat surface treatment is using a plasma thermo-chemical process which takes place in electrolytic bath. The result is a thick coating with good wear and corrosion resistant properties.

Through the control of the electrical parameters and the composition of the electrolyte the coating can be designed for specific material substrates and applications.

Properties:
Microhardness: 1400-1800 HV50 grams
Thickness: up to 100 µm

Applications:
Tribological, wear and corrosion resistant coatings on Al alloys and Mg alloys for components in aerospace, marine and automotive industries.

1. Anti-fretting wear - modified ASTM G77-97
Results: Average friction force of 1.5 lbs., COF of 0.03

2. Anti-friction - ASTM G99 (sapphire pin)
Results: no wear marks

3. Corrosion resistance - ASTM B-117 / 07
Results: coating not corroded after 400 hrs.
