Experimental comparative study of chrome steel pin with and without chrome plated cast iron disc in situ fully flooded interface lubrication

Abstract

This paper reports the findings of an experimental study pertaining to the tribo dynamic investigations of contacts formed between chrome base pin and cast iron/chrome plated cast iron discs in situ conditions. Pin on disc geometrical configurations were employed for conducting the experiments at different operating parameters using SAE-15W40 lubricating oil. The fully flooded lubricating condition was insured by directed supply of lubricant at the interface. The friction coefficient, wear rate, vibration amplitude, temperature rise and sound intensity were measured at different loads (varying in the range of contact pressure 1.9–3.1 MPa) and sliding speeds (2–10 m s−1) for the travelling distances between 1000–5000 m. Based on experimental investigations, reductions in the friction coefficient and wear rate were recorded for the chrome steel pin/chrome plated cast iron disc in comparison to chrome steel pin/cast iron disc contact. However, increases in the temperature rise, vibration, and noise were recorded with chrome steel pin/chrome plated cast iron disc contact.
