In this paper, effect of heat treatment on the microstructures and wear properties of laser alloying (LA) composites is investigated. LA of the T-Co50/FeSi/TiC/TiN/CeO2 mixed powders on substrate of 45 steel can form the hard composites, which increased the wear resistance of substrate greatly. Such LA composites were investigated by means of a scanning electron microscope (SEM) and a transmission electron microscope (TEM). The tempering promoted the growth of the block-shape hard phases, favoring an enhancement of the integrity of block-shape hard phases; and tempering also improved greatly the formation mechanism, guarantying the composites to have enough ability of intensity transfer. This research provided essential experiment and theoretical basis to promote the application of the laser and heat treatment technologies in the field of surface modification. © 2014 World Scientific Publishing Company.

The spinning solution for polycrystalline mullite fiber was prepared by sol-gel method, using aluminum powders, HCl and silica sol as raw materials, deionized water as solution. The effect of the amount of PVA on the spinnabiltiy of sol was inspected. The infrared absorption characteristics and the behavior of rheology of the spinning sole were studied respectively by infrared absorption spectra of FTIR and rotational rheometer. The phase composition of the precursor fibers after heat treatment was analyzed with the help of XRD. The results show that the sol is non-newtonian fluid with shear thinning property and presents no tube siphon phenomenon when the amount of additives of PVA is in the range of 2%-4%. The sol with solid content in the 30%-40% and viscosity in the 4-7 Pa·s has excellent spinnability, with sol spinnability index of 25-26 cm/s. In the spinning sol there are linear polymer chain structures of Al-O-Si, which are benefit to spinning. The main crystal phase of fiber calcined at 1050℃ is mullite. ©, 2015, Chinese Ceramic Society. All right reserved. Source
