The vc - fe surface composite shows high wear - resistance, it ' s wear - resistance is 4. 20 times as that of chilling respectively. with the content of v increasing, it ' s rigidity and wear - resistance increases continually. more vc grains gained, and well distributed, better wear - resistance the vc - fe surface composite will show. ( 7 ) surface cermet composite was formed by the means of cast - sintering technique, with the help of adding wc grains and the quantity of heat sent out from the reaction v + c vc, the carbide cermet quality percent exceeds 60 %
在重載干滑動摩擦條件下, vc一fe表面復合材料顯示了很高的耐磨性,其相對耐磨性是可淬硬鑄鐵的4 . 2倍:隨著含v量的增加, vc一fe表面復合材料的鑄態硬度和耐磨性不斷提高, vc顆粒越多,分佈越均勻,表面復合材料的耐磨性就愈好。 -
Results show that zro2 - ni cermet has clear crystalline interface and uniform distribution. its crystal size is 0. 3 p m. through analyzing the data of specific heat of zro2 - ni cermet, it reveals that adulterating cobalt can enhance the wetting quality of ni and zro2
用xrd 、 sem研究了zro _ 2 - ni - co金屬陶瓷的相結構和形貌,確定了合適的燒結溫度,結果表明,材料的晶粒大小和分佈十分均勻,晶界清晰,粒度在0 . 3 m左右。
