| Abstract: | The high phosphorus gray iron specimens,taken from 135 diesel cylinder bush,were subjected to medium-temperature phosphating. The phosphating surface was surveyed by SEM. It was revealed that the phosphating film exhibits phosphate druse random distributed.The phosphating process,including composition of phosphating bath,phosphating temperature and time at temperature,will exert an appreciable influence on the nucleation,growth,morphology and performance of the phosphate crystals. |
