Thermal Stability Of

H13 steel is prone to insufficient high temperature wear resistance due to thermal wear under high temperature conditions. To improve high temperature wear resistance of H13 steel, the maraging steel coating with low-nickel was successfully prepared owing to excellent thermal stability. Sliding wear tests at 400, 500 and 600 °C were carried out for the laser cladding coating and H13 steel to comparatively investigate their high temperature wear performance and mechanism. The microstructure, phases, hardness and thermal stability of the maraging steel coating were also studied. The results showed that the maraging steel coating possessed excellent high temperature wear resistance and effectively improved the high temperature wear resistance of H13 steel by laser cladding. The superior thermal stability of maraging steel played an important role in improving its high temperature wear resistance.

High-Cr cast-penetrated layer contained nanometer ceramic particles was formed on the surface of the medium carbon steel ZG250-470 by adding nanoTiN intermediate alloy powder to cast-penetrated agent. Microstructure and wear resistance of the strengthened cast-penetrated layer were studied. The results showed that: compared with not adding intermediate alloy, there were finer and more uniform microstructure and better high temperature and high speed wear performance of strengthened cast-penetrated layer strengthened by nanoTiN intermediate alloy. Strengthening effect would be best by adding the intermediate alloy containing rare earth. By adding intermediate alloy containing Ni, the best high temperature wear resistance of cast-penetrated layer could be obtained.

In this research, the tribological and dynamical characteristics of a brake pad with multiple blocks are investigated using experimental and numerical methods. A dynamometer with a multiblock brake pad configuration on a brake disc is developed and a series of drag-type tests are conducted to study the brake squeal and wear behavior of a high-speed train brake system. Finite element analysis is performed to derive physical explanations for the observed experimental phenomena. The experimental and numerical results show that the rotational speed and braking force have important influences on the brake squeal; the trends of the multiblock and single-block systems are different. In the multiblock brake pad, the different blocks exhibit significantly different magnitudes of contact stresses and vibration accelerations. The blocks located in the inner and outer rings have higher vibration acceleration amplitudes and stronger vibration energies than the blocks located in the middle ring.
