Abstract

Highlights: Critical assessment of laser surface texturing and effect of types of lasers viz. nanosecond, picosecond, and femtosecond pulsed lasers for micro/nano texturing has been discussed. Effect of laser surface texturing process design and parameters has been discussed and effect of surface modification using laser surface texturing in lubrication & wear, thermal sprayed coatings applications is presented. Application of laser surface texturing for wettability enhancement of the engineering materials is presented. Abstract: Laser surface texturing is a relatively well-known technique for enhancing the surface topography of engineering materials. Lately, several surface texturing approaches like nanosecond, picosecond and femtosecond laser texturing have been adopted for surface modification and to study the deterministic behaviours of texturing patterns with different shapes and sizes. Due to superior texturing accuracy and flexibility, laser surface texturing has been used to enhance lubrication and wear behaviour, mechanical interlocking at coating substrate interface, and creating superhydrophobic surfaces. The present paper review aims to discuss the recently enhanced tribological aspects using laser surface texturing for engineering surfaces. This study has highlighted the different laser surface texturing processes and future directions of surface modification to enhanced adhesion bond strength in surface coatings, improved lubrication for surface contact, and fabrication of superhydrophobic surfaces.
