TiC is built on carburizing on surface of titanium alloy, with very high hardness. But TiC coating and substrate adhesion is poor, hampering actually used. Higher temperatures will cause titanium carbide grain growth rate:

1. firing temperature. Final sintering temperature of high manganese steel bonded carbides of titanium carbide and generally the 1420 ¡æ more appropriate. Sintering temperature should not be too high. Even loss of binding phase into a liquid metal, which brought together hard phase occurs adjacent to, and raised, forming fractured source. This is the analysis of bonding between grains of hard phase is less reason. Sintering temperature too low, of course, will make alloy less burn. Degumming, restore, and especially in 3 stages of liquid-phase sintering.

2. the heating rate of sintering. This type of alloy heating speed should not be faster. To strictly control the heating speed and holding time. Because in low temperature degumming stage, pressure billet release suppressed stress and forming agent volatile of process, if warming speed fast, is for forming agent too late volatile and liquefied Hou into steam, makes pressure billet occurred burst or micro-crack phenomenon; 900 ℃ above of restore stage, to let pressure billet has enough of time off to by with raw materials powder (as Mn2Fe Middle alloy) in the of volatile real and oxygen; into liquid phase sintering stage Shi, also to slowed warming speed talent makes pressure billet full alloy of.
