Effects of morphology parameters of sinusoidal texture on tribological properties under dry friction.

Purpose: This paper aims to investigate the influence of sinusoidal texture (ST) with different morphology parameters on the corresponding tribological effects. Design/methodology/approach: The STs with different amplitudes, ranging from 0.05 to 0.3 mm, and frequencies, ranging from 5 to 17.5, are fabricated using nanosecond pulsed laser equipment. The friction experiments and the finite element analysis method are combined to investigate the tribological properties, under dry friction conditions. Findings: Test results show that when the amplitude is 0.15 mm and frequency is 10, ST surface has the lowest friction coefficient of 0.373, and exhibits great anti-friction effect. It also possesses a complete texture edge after friction. The friction reduction effect of ST with larger or smaller amplitude and frequency is worse. Originality/value: The results of this study can provide a guidance for the design optimization of ST of reciprocating sliding contact surfaces, under dry friction conditions. [ABSTRACT FROM AUTHOR]
