铸态硬度 meaning in Chinese
as-cast hardness
casting hardness
Examples
- 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
铸造烧结时，过热铁水的巨大热流密度冲击、粉料压坯中的碳化反应的放热以及压坯中少量液相的产生使压坯的烧结速度大大提高，此时属瞬间液相烧结，在十几分钟内烧结过程即可完成，可达到很高的致密化程度。 ( 6 )铸态下vc一fe表面复合材料具有很高的硬度，其铸态硬度) 60hrc 。 - 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 %
在重载干滑动摩擦条件下， vc一fe表面复合材料显示了很高的耐磨性，其相对耐磨性是可淬硬铸铁的4 . 2倍:随着含v量的增加， vc一fe表面复合材料的铸态硬度和耐磨性不断提高， vc颗粒越多，分布越均匀，表面复合材料的耐磨性就愈好。
