Potential Studies of Waterjet Cavitation Peening on Surface Treatment, Fatigue and Residual Stress

Machining is undeniable in the manufacturing firm. In order to meet the emerging needs of engineering applications, new materials are developed and they create a complication in the machining owing to its extensive properties. The manufacturing industries are being pulled to use the unconventional machining to machine these materials. To improve the life of the end product, engineers adopt various technologies and follow different methodologies. Waterjet Peening (WJP) is one among the technologies where the surfaces are hardened by means of high-pressure water thereby provoking the beneficial residual stress into the surface layers for some thickness. WJP is also be called as the green technology because of its various advantages like eco-friendly, non-pollutant, no HAZ, ability to machine any materials, etc., then another unconventional machining. In this paper, the potential study has been carried out on WJP by considering the surface treatment, residual stress, and the fatigue. As WJP is governed by various parameters, the influences of some significant parameters are detailed in this work. Only a considerable amount of work has been exposed on this machining practice. Hence, the researchers have felt that the review of WJP machine will enhance the machine utilization to a greater extent.
