Wear Evaluation

In this research work, two types of cryogenic treatment such as deep cryogenic treatment (-196oC) and shallow cryogenic treatment (-80oC) have been adopted for wear resistance to increase in AISI 440C bearing steel. This paper has been focused to increase Wear Resistance (WR) through deep micro structural analyses, and also attention has been made to correlate the microstructure with the wear character of Deep Cryogenic treated (DCT) specimens, Conventional Heat Treated (CHT) specimens and Shallow Cryogenic Treated (SCT) specimens. Micro structural examinations have been carried out in the specimens through Scanning Electron Microscopy (SEM), Energy Dispersive Analysis of X-ray (EDAX) and X-Ray Diffraction (XRD). Wear characteristics of AISI 440C bearing steel has been studied. The outcome of the research disclosed that the DCT specimens have higher wear resistance than SCT and CHT specimens. The effective wear mechanisms recognized were the constitution of white layers and delamination of white layers. The microstructures of the materials have been varied through heat treatment process. The modification of Secondary Carbides (SCs) precipitation characteristics and its reduction of retained austenite in the microstructure have been correlated with wear character and these are the liable mechanism to raise the wear resistance of bearing steels through DCT.

The aim of this research was study the influence of the Deep Cryogenic Treatment (DCT) on the microstructure transformation and materials properties of beryllium copper alloy (CuBeZr alloy). Microstructure analysis such as size, shape and number of precipitates were studied by Optical microscopy (OM) and Scanning Electron Microscopy (SEM). Microstructure analysis showed that transformation into the rod shape precipitates appeared after the process. The dispersion of CuNi precipitates and CuNiZr precipitates in the ⍺ matrix after deep cryogenic treatment was found to be increased. The change in number of CuNi precipitates and CuNiZr precipitates led to an increase in hardness and wear resistance. The maximum increase in hardness of 11% was observed with 48 hours soaking time with a reduction in surface wear of approx. 60%.
