摘要：
Coatings obtained with magnetron sputteringexhibit a columnay structure. There are nodulardefects distributed in the coatings, which arefomed by radial growth of columnay grains ingroups. The fomation of them does not necessarilydepend on surface asperities of substrate. Thecolumnar grain boundaries are enriched in oxygen,which causes microporosity in the intercolumnarregions.
