coating composition meaning in Chinese

涂层成分
涂料组分

Bias voltages exert a small effect to the residual stress of al coatings , but do a considerable effect to the coatings composition such as the preferential sputtering in al - zn coatings at - 100v
偏压对铝镀层残余应力的影响较小，且总体变化不大，但在- 100v偏压下， al - zn镀层的成分有明显的择优溅射现象。
The main experiment results are as the following . the coatings composition and microstructure are influenced significantly with the different techniques or process parameters . at - 100v low bias voltage applied to uranium substrate , all of three coatings are closely dense , while the al coatings are completely open dentritic at - 300v
在基体上施加- 100v低偏压时， al 、 al _ 2o _ 3和al - zn镀层三种镀层的组织均致密，但在- 300v偏压时，铝镀层组织呈开放式结构，致密性差。
