灰铸铁%中温磷化%磷酸盐晶体
灰鑄鐵%中溫燐化%燐痠鹽晶體
회주철%중온린화%린산염정체
gray iron%meidium-temperature phosphating%phosphate crystal
对取自135型柴油机气缸套的高磷灰铸铁试样进行了中温磷化处理。对磷化表面进行了扫描电镜观察。结果发现，磷化膜形态为无规律分布的磷酸盐晶簇。磷化工艺，包括磷化液成分、磷化温度和时间，对磷酸盐晶体的形核、生长、形态及性能有明显的影响。
對取自135型柴油機氣缸套的高燐灰鑄鐵試樣進行瞭中溫燐化處理。對燐化錶麵進行瞭掃描電鏡觀察。結果髮現，燐化膜形態為無規律分佈的燐痠鹽晶簇。燐化工藝，包括燐化液成分、燐化溫度和時間，對燐痠鹽晶體的形覈、生長、形態及性能有明顯的影響。

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.
