In the oxygen-rich conditions must take into account the effects of oxygen absorption hardening depth . Only under conditions of thin layer thickness in a vacuum or in argon - methane atmosphere,grade 3 titanium it may penetrate the toner to form a sufficient adhesive strength as compared with this, using a gas agent may form hard and particularly good adhesion titanium carbide hardened layer. While the: and 10201: conditions at temperatures between formation and hardening exhibition in between.medical titanium bar With increasing thickness of the titanium carbide layer becomes more brittle and tend to peel t To avoid leaving alkyl decomposition of carbon inclusions invasion of titanium carbide layer should be about 2% volume fraction of the provisions Rui alkyl dose additive gas in an inert gas. When using propane, methane and the use of additives on the formation of when low surface hardness. When the adhesive force reaches Wu Mao conditions when using propane gas although the measured thickness of the hardened layer is very thin, but it has the best wear resistance. Absorption of hydrogen in the gas agent type conditions using either, but had to remove it again when the vacuum annealing
