Research on the tribological properties of iron borides as diffusion coatings

Friction tests of diffusion boride coatings were performed by rod-plate and rod-sleeve techniques at loads of 147-1960 N. It was shown that the Fe 2 B layer can demonstrate plastic deformation under the conditions. In the case of M11 (AISI) alloyed steel, diffusion boriding results in the extremely...

Summary:Friction tests of diffusion boride coatings were performed by rod-plate and rod-sleeve techniques at loads of 147-1960 N. It was shown that the Fe 2 B layer can demonstrate plastic deformation under the conditions. In the case of M11 (AISI) alloyed steel, diffusion boriding results in the extremely favorable hierarchical self-organization of defensive coatings and high wear resistance. The alloying of iron borides by chromium contributes to an increase in plasticity in these phases and a decrease in the coefficient of friction. The influence of the nature of the substrate and quenching treatment on the surface-relief characteristics before and after tribological tests, as well as on linear wear, has been determined.
