Effect of strength and deformation of die steel deposited metal on thermal fatigue resistance 多层膜中巨磁电阻效应及与微结构的关系
Bend test for ductility of electrodeposited and autocatalytically deposited metal coatings on metals 金属表面电解沉积和自动催化沉积金属镀层延展性的弯曲试验
Classification and testing methods for deposited metal of submerged arc welding for carbon steel and low alloy steel 碳钢及低合金钢埋弧焊堆焊金属的分级及试验方法
The microstructure and porosity of the deposited metal can be systematically manipulated by the use of osmotic pressure 利用渗透压的新技术可控制膜的微观结构和孔隙率。
The results show that the absolute humidity of the welding environment has great influence on the hydrogen diffusion , and that the greater the absolute humidity , the higher the content of hydrogen diffused in deposited metal 结果表明,焊接环境的绝对湿度对超低氢焊条熔敷金属中扩散氢含量有较大影响,绝对湿度越大,焊缝金属中扩散氢含量越高。
Abstract : by measuring the content of hydrogen diffused into the deposited metal under different temperature and humidity in the first environmental welding laboratory of our institute , the influence of the environmental conditions on the hydrogen diffusion was investigated 文摘:通过在温湿可调焊接实验室中进行不同环境条件下的测氢焊接试验,研究了环境条件对熔敷金属中扩散氢含量的影响。
The result showed that the interpenetration network structure between polymeric and deposited metal has been observed under a scanning electronic microscope and optical microscope . the experiments showed that copper deposition gradient distribution and crystal structure were greatly influenced by the the ph value of electrochemical reduction medium solution and the size , number and distributing of microporous in swelling cathode film 用扫描电镜和体式显微镜对制备的pmgcf进行了分析,结果表明:制备的pmgcf样品的金属沉积层梯度分布均匀,在一定的电化学条件下金属铜和聚合物基体形成了互穿的立体网状结构。
The mpgcfs observed by sem have such characteristics as the concentration of the deposited metal varied gradiently across the section of the film . one side is deposited phase , which is mainly composed of predominant metal and minal polymer ; and the other is undeposited phase , which is polymer matrix and hardly contains m etal ; and between the two side is the transition phase , where the polymer and metal interpenetrated 结果通过扫描电镜发现,合成的mpgcf具有以下的特征:金属相在膜的厚度方向上呈梯度分布,膜的一侧为致密的金属,另一侧为不含金属的聚合物基体,两侧的中间为聚合物和金属互相贯穿的过渡层。
