Title
Hardness Distribution in Ag - Cdo Layer obtainted by Internal Oxidation
이동녕Dong Nyung Lee, 박평주Pyung Choo Park
Abstract
Hardness distributions in Ag-CdO layers obtained by the internal oxidation have been studied laying emphasis on the effects of impurity elements added. The hardness of specimens including 0.1% aluminum or beryllium was larger than that of specimens without the elements, whereas the hardness of specimens with 0.1% antimony or copper was about the same as that of specimens without them. The specimens oxidized at lower temperatures were harder than those oxidized at higher temperatures. The hardness of specimens decreased with increasing depth from the surface. These phenomena were discussed based on the particle size distribution and particle shape.
