Abstract

This study aimed to explore how Mo content impacts the microstructure and properties of (Ti, W) C-CoCrNi-based cermets. Samples with varying Mo content were prepared by using powder metallurgy. Various methods, including X-ray diffraction analysis, scanning electron microscopy observation, hardness testing, and magnetic property measurements, were employed to systematically study the role of Mo in the cermets. The study showed that as Mo content increased, there was a gradual reduction in the grain size of the material and the grain distribution became uneven. The addition of 1~5 wt.% Mo did not alter the magnetism of the cermets, and all cermets presented paramagnetism at room temperature. As the Mo content increases, the bending strength of cermets gradually decreases. The hardness of the cermets increased from 86 HRA to 87.9 HRA as Mo content was raised from 0 to 1 wt.%. However, as the Mo content continued to increase, the hardness values showed little change.
