Microhardness test indicated that the Ir Re Cr N multi-component coating exhibited compatible hardness with the Ir Re binary hard films, and the surface hardness was better than that of the Ir Pt film.
The as-prepared SiC/La2Zr2O7 multi-component coating was well bonded to the substrate, which might be associated with the newly formed La4.67(SiO4)3O phase, with a uniform thickness of 85.8 μm.
In the present study it was attempted to develop a multi-component coating by laser cladding process using a pre-placed powder mixture containing Ni5Al (50 vol%) + hBN (10 vol%) + B4C (20 vol%) + SiC (20 vol%) on substrate of Ti-6Al-4V to improve its tribological performance.
This case study points out the possible participation of other components (coating materials), beyond MMVFs, in the etiology of pneumoconiosis.
Combined with data in Figure 5 a, the TRPS traces reflect the dynamic nature of the dispersion; SWCNH-ox in 1% FBS appear to be poorly stabilized due to insufficient serum in the media, resulting in a mix of particles with variable amounts of serum components coating their surfaces and potentially indicating partial coverage.
