铸造碳化钨 meaning in Chinese
cast tungsten carbide
Examples
- It is preferable to use tungsten carbide of fine grain size for such build - up welding
堆焊采用的铸造碳化钨颗粒，以细的为佳。 - Cast tungsten carbide
铸造碳化钨 - Their lifetime can be prolonged if they are repaired with cast tungsten carbide powder
采用铸造碳化钨修补后，可以延长使用寿命。 - The age hardening characteristic of as - cast cu20ni20mn and cu20ni35mn alloys and the interface characteristic between the alloy and cast tungsten carbide were studied , and on the basis of this study , composites of cu - ni - mn alloy reinforced with different volume fraction ( 0 - 45vol . % ) and different size ( 42 - 362 m ) of cast tungsten carbide particles were made by vacuum hot - pressing liquid sintering technology . pin on disk two body abrasion tests have been performed with different size of sic abrasive under different loads
本文研究了铸态cu20ni20mn和cu20ni35mn合金的时效硬化特性及其与铸造碳化钨的界面特性，并在此基础上以不同尺寸( 42 362 m )的铸造碳化钨颗粒为增强体，采用真空热压液相烧结技术制备了不同颗粒含量( 0 45vol . )的铸造碳化钨颗粒增强cu - ni - mn合金基复合材料；以不同粒度的sic为磨料，在不同载荷条件下利用销?盘磨损试验机测试了复合材料的二体磨料磨损性能。 - The results show that the composites were more wear resistant than the matrix , contributing to the " volume effect " and " size effect " , the wear resistance increases with the particle content and size . the composite shows better wear resistance than high chromium cast iron material especially in low load and fine abrasive test condition . the results also indicate that the composite strengthened by ageing treatment was more wear resistant than as - cast composite
磨损试验结果表明，铸造碳化钨颗粒增强cu - ni - mn合金基复合材料具有比较高的抗磨料磨损能力，而且其耐磨性随着铸造碳化钨颗粒体积分数及尺寸的增大而提高，表现出了强烈的“体积效应”及“尺寸效应” ，尤其是在低载荷、细磨料磨损条件下，复合材料表现出更好的而寸磨性，即使与高铬铸铁( cr28 )相比也有很大程度的提高。
