Study on Effect of Laser Shock Peening as a Pre-Treatment on Fatigue Performance of Hard-Chorme Plated 15–5 PH Stainless Steel
15–5 PH SS is a martensitic precipitation-hardening stainless steel (SS) with high strength (Yields at 1000 MPa) and good corrosion resistance. The material finds wide applications in aerospace structural components, defense and offshore oil & gas industry where high strength, corrosion resistance and toughness are required. High tensile strength of precipitation hardening stainless steels can be realized after a heat treatment process that leads to precipitation of minor elements (Cu/Al/Mo etc.) in a martensitic or austenitic matrix [1, 2, 3, 4]. The reduced distortion during low temperature heat treatment makes these steels particularly suitable for intricate parts requiring machining and welding.
Hard chrome electroplating is a widely used surface treatment for parts operating in high wear and erosion environments, due to its high hardness and low coefficient of friction. Hard chrome plating is generally carried out by electrolytic means while using chromic acid (CrO3)...
