To form a thin film of inert phosphate on the metal surface. Process to reduce the rateofcorrosion.
在金属表面形成的惰性的磷酸盐薄膜。该工艺可以降低金属被腐蚀的几率。
2
While extending the duration ofcorrosion sufficiently, the rateofcorrosion was accelerated by the appearance of a large number of microscopic cracks on oxide surface.
随腐蚀反应的进一步进行,锆-4合金由于其表面形成大量微裂纹而出现加速腐蚀现象。
3
Because of the place obstruction ofcorrosion products in the surface of the alloys, while corrosion time is at 120 minutes above, the corrosion rate descends to the stable value in 48 hours.
