defect in coating 中文意思是什麼
defect in coating
解釋
覆層缺陷-
With plating time going on, the nano - polycrystal gathering grows in two dimensions, and the new nano - polycrystal layer appears simultaneously on the formerly formed nano - polycrystal surface. because the boundary and defect densities in quenched and tempered 45 steel is higher than those in annealed steel, the nano - polycrystal gatherings formed at its surface at the beginning of electro - deposition are more concentrated, and then their size is smaller. the microstructure of the ni - p alloy coating has closed relation with its phosphorus content with the increase of phosphorus content, the microstructure of coating turns from nano - crystalline to the amorphous
隨著施鍍時間的延長,納米晶聚晶體在橫向二維生長的同時,在納米晶聚晶體的表面上也進行著三維方向的新的一層聚晶體的生長;在調質態45鋼表面,由於其具有比較高的晶界和缺陷密度,因此在沉積初期,納米晶聚晶體的成核密度也較大,從而在二維方向聚晶體的尺度較小,鍍層沉積初期表現為緻密細小的鱗片狀組織。 -
A defect in the magnetizable surface coating ( for example, on magnetic disc ) consisting of a raised or thick area
在磁性表層上(如磁盤上)的缺陷,包括隆起的區域或厚的區域。
