| Abstract Scope |
Conventionally, surface texture is fabricated using laser-based techniques. However, this study introduces an alternative method that employs a masking technique in combination with Micro-shot Peening (MSP) to produce complex and functional surface textures. Experimental results demonstrated that this approach significantly reduces the coefficient of friction under lubricated conditions, achieving a maximum reduction of 56 percent (from 0.122 to 0.053). Furthermore, the textures generated by MSP exhibit pronounced surface hardening, with hardness increasing by up to 1.6 times (from HV346.3 to HV553.0). This combined improvement in tribological and mechanical performance underscores the potential of MSP with masking as a green and cost-effective solution to enhance wear resistance, extend material lifespan, and lower energy consumption across various engineering applications. |
