Microstructural Characteristics and Wear Properties of NiCr/Cr₃C₂-WS₂ Self-Lubricant Wear-Resistant Composite Coating on Ti6Al4V by Laser Cladding

Abstract:

The self-lubricant wear-resistant NiCr/Cr₃C₂-10%WS₂ coating and wear-resistant NiCr/Cr₃C₂ coating were obtained on Ti6Al4V by laser cladding. Microstructure of the coatings was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and X-ray energy dispersive spectrometer (EDS). The wear properties were evaluated using a ball-on-disc wear tester under dry sliding condition. The results show that the laser cladding NiCr/Cr₃C₂-10%WS₂ composite coating has good friction-reducing and anti-wear capabilities at ambient.
