Purpose:
Deposition of antifrictional coatings on wearing metal surfaces. The coating's electroplating technology is based on utilization of triple-component's alloys with higher hardness and wear resistance in comparison with two-component's alloy Pb-Sn.
Region of application:
manufacturing or restoration of frictional nodes ( e.g., bearing bushes)
Technical parameters:
| frictional coefficient | £ 0.06 |
| microhardness, H50, Mpa | 90–115 |
| coating's adhesion to substrate, N/mm2 | 800 and more |
| destruction strength, kg | up to 500 |
| degree of attrition in comparison with Pb-Sn alloys, times | less in1.5–2 |
| deposition rate, mm/min | 1–1.5 |
Advantages:
- simplicity of electrolyte's exploitation
- high working thickness of coatings (up to 300 mm)
- possibility of simultaneous coating's deposition on large detail's quantity
- good running-in of rubbing surfaces
- low wearing of counter-body
Options for collaboration:
You can purchase the technology know-how. We can manufacture small series of miniature articles with deposited antifrictional coatings.
