Experimental Study and Analysis of Coefficient of Friction for Mild Steel Under Various Lubrication Conditions
Abstract: The coefficient of friction plays decisive role in the metal-forming processes. This study focuses on determination of the coefficient of friction between work piece and lubricants using ring compression test by experiments physical modeling and finite element (FE) simulation. A series of ring compression tests were carried out to obtain friction coefficients of mild steel under lubricants including boric acid, Vaseline, grease and dry conditions. According to Male and Cockcroft …

Study the effect of lubrication on hardness in the ring compression test
Abstract: Mild Steel is commonly used to produce automotive parts such as shafts, gears and bearings. This paper focuses on the hardness distribution in the mild steel ring specimen after compress under rigid dies. Three different types of lubricants namely boric acid, Vaseline, grease and dry condition were employed as lubricants and the coefficient of friction corresponding to the lubricant evaluated using standard ‘Ring compression test’. The strain distributions obtained from …
