The effect of Ag electroplated layer on temperature-adaptive lubrication behavior of the CoCrMo coating with a texture interface
The CoCrMo coating (CCM coating) was prefabricated by laser cladding. The effects of textured interface prepared by laser texture technology and Ag electroplated layer on the tribological properties of the CCM coating were systematically investigated. Compared to the CCM coating and Ag electroplated...

| description | The CoCrMo coating (CCM coating) was prefabricated by laser cladding. The effects of textured interface prepared by laser texture technology and Ag electroplated layer on the tribological properties of the CCM coating were systematically investigated. Compared to the CCM coating and Ag electroplated coating on an untextured CCM surface (CA coating), the CoCrMo–Ag composite coating (CTA coating) demonstrates the lowest average COF and wear rate over a wide temperature range, especially at 800 °C (0.15 and 3.89 × 10−6 mm3/(N·m)). Friction experiments conducted with various durations revealed that the CTA coating consistently exhibits superior tribological properties. The textured interface retains Ag and provides long term lubrication at medium-low temperature. The in-situ formation of lubricating phases between Ag layer and elements in the CCM coating enhances lubricating performance at elevated temperature. The composite coating exhibits superior temperature adaptive lubricating performance over a wide temperature range due to the novel composition and microstructure design. |
