  • ABSTRACT: Slide burnishing (SB) and roller burnishing (RB) are static mechanical surface treatment methods, based on surface plastic deforming of the metal components and intended to improve the surface integrity (SI) of these components. This article presents the outcomes of comparison between slide diamond burnishing and RB under “micro-hardness” criterion. Due to the sliding friction contact, SB achieves significantly bigger micro-hardness compared to RB. The significant increase of burnishing force leads to slightly increase of the micro-hardness.
