Must have working knowledge of cmm , micro - height , hardness tester , surface gage , calipers , and additional equipment 必须有关于cmm ，高度测量，硬度测试，表面测量，齿轮等设备知识。
The results indicated that the hardness of the coating decreased because of the addition of the soft particles - ptfe 硬度测试结果表明， ptfe软质微粒的加入，使得复合镀层的硬度显著降低。
The determination of the hardness value from the auxiliary quantity by employing the relevant equation defining the hardness testing method 透过界定硬度测试法的有关方程式，从辅助数量测定硬度值。
Sintered ferrous materials , carburized or carbonitrided - determination and verification of case hardening depth by a micro - hardness test iso 4507 : 2000 烧结铁类材料.渗碳或碳氮共渗.用微型硬度测试法测定
Sintered ferrous materials , carburized or carbonitrided - determination and verification of case - hardening depth by a micro - hardness test 烧结铁类材料.渗碳或碳氮共渗.用微型硬度测试法测定和验证外层淬火的深度
By means of chemical composition analysis , hardness testing , non - metallic inclusion examination , metallographic examination , macro and micro - fractography fracture analysis were conducted 对剃齿刀断口进行了宏、微观检验、化学成分分析、硬度测试和非金属夹杂物及显微组织检验。
Using the device , we tested two groups of samples that included the steel of 40cr and the steel of 65mn , got a single - valued relationship between displayed value on the device and tempering hardness 对以40cr和65mn为代表的回火件进行了硬度测试，得到了其回火硬度与数显值之间良好的单值对应关系。
Ferrous metals , non - ferrous metals , ic thin sections , coatings , ply - metals ; glass , ceramics , agate , precious stones ; hardness testing such as that on the depth and the trapezium of the carbonized layers and quench hardened layers 黑色金属、有色金属、 ic薄片、层压金属、表面涂层；玻璃、陶瓷、玛瑙、宝石等；炭化层和淬火硬化层的深度及梯度的硬度测试。
In addition , another experiment was carried out that the powdered aluminum and copper was pressed in one die with a same pressure and infiltrated them after that with a hardness test of the aluminized copper sample and the obvertion of its microstructure 本文还试验了通过铜粉与铝粉在同一模具内，同一压力下压制后熔渗的实验，并对渗后的试样进行了硬度测试和微观组织的观察。
