Titanium nitride containing higher content of nitrogen has been prepared by self-propagationhigh-temperature synthesis of titanium powder in pressurized nitrogen atmosphere,and the ef-fects of bulk density of reactants,nitrogen pressure and diluent content on the combustion wavevelocity and conversion to titanium nitride were investigated.

By using the vacuum ion plating technique,nitriding,titanium nitride and their complex coatings are plated on AISI D2 steel,and the finite element analysis(FEA)and experiments are employed to investigate their wear resistance.

Composition and structure of TiN film prepared by plasma-based ion implantation;

The experiment results show that TiN film on chamber surface with proper characteristics can be achieved at 80~90 Pa and 160~180 ℃ of coated surface temperature.

A surface treatment setup of coating TiN film on the inner face of stainless steel pipe vacuum chamber for accelerators at low temperature is described.

TiN multi-permeated layers were formed on the steel surface with diffusion layer and deposition layer by means of both double glowdischarge surface alloying process and reactive sputtering.

This paper analyzes the synthesis of TiB2-TiN composites by SHS in terms of reaction process ratio of raw materials and the velocity of combustion wave,and the effect of each of these factors on the process.
