With the correct compound designing, a composite layer with thickness of 1. 5to 6 millimeters was formed on the surface of casting by means of cast - sintering technique
通過合理的成分設計和工藝參數的優化選擇，利用鑄造燒結技術，在鑄鐵件表面獲得了一層厚為1 . 5 6mm的耐磨復合材料層。Sintering speed increased greatly with the help of great quantity of heat of the molten iron, the great quantity of heat sent out from the carbonizing reaction and a little quantity of liquid, this sintering type is an instantaneous sintering, the sintering compacting can carry completely in a few minutes, the degree of sintering compacting is very high. ( 6 ) the vc - fe surface composite has high rigidity, it ' s rigidity exceeds 60hrc, under condition of dry sliding friction and overloading
鑄造燒結時，過熱鐵水的巨大熱流密度沖擊、粉料壓坯中的碳化反應的放熱以及壓坯中少量液相的產生使壓坯的燒結速度大大提高，此時屬瞬間液相燒結，在十幾分鐘內燒結過程即可完成，可達到很高的緻密化程度。 （ 6 ）鑄態下vc一fe表面復合材料具有很高的硬度，其鑄態硬度） 60hrc 。The speed became fast at the temperature 1050. the reaction could carry completely when billets was kept in vacuum tube for 3 hours " at 1050 temperature, under the striking of great quantity of heat when the molten iron poured into the mold, the reaction was blazed rapidly and continued at a high speed. the diffusible speed of v and c was very fast because the billet was heated over 1300 in a moment, so the reaction ca n complete in a few minutes
（ 5 ）碳化反應v + c vc在900左右開始發生，此時是固相反應，反應速度較慢，反應不能進行完全，隨溫度升高，該碳化反應的速度加快，在1050保溫3小時可以進行完全，在鑄造燒結時在過熱鐵水的巨大熱流密度沖擊下， v + c vc立即被激發，並以很快的速度進行，由於坯塊被加熱到1300以上，此時c和v擴散速度很快，因此鑄造澆注后的幾四川大學碩士學位論文分鐘內反應可以進行完全。
