采用X射线衍射仪（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）等研究了糖心产精国品免费入口*完整版（Q&P）糖心产精国品免费入口*完整版后30Cr13糖心产精国品免费入口*完整版的物相组成和显微糖心产精国品免费入口*完整版的演变规律，并利用动电位极化法对不同工艺糖心产精国品免费入口*完整版的糖心产精国品免费入口*完整版在3.5%（质量分数）NaCl水溶液中的腐蚀行为进行了分析。结果表明：220Q盐浴淬火试样和220P一步法糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版试样的残余奥氏体体积分数小于3%，随着二步法糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版中配分温度从300℃上升至500℃，30Cr13糖心产精国品免费入口*完整版的残余奥氏体含量呈现先增加而后降低的趋势，在配分温度为400℃时取得最大值；220Q和220P试样的糖心产精国品免费入口*完整版都由板条状马氏体组成，经过二步法糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版后，糖心产精国品免费入口*完整版的基体糖心产精国品免费入口*完整版也由板条马氏体组成，此外在马氏体板条间有白亮条状或者颗粒状M₃C型碳化物出现；不同糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版的30Cr13糖心产精国品免费入口*完整版的耐均匀腐蚀性能差别不大；二步法糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版试样的点蚀电位高于盐浴淬火试样和一步法糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版试样的。

The phase composition and 糖心产精国品免费入口*完整版 evolution of 糖心产精国品免费入口*完整版 30Cr13 after quenching and partitioning (Q&P) 糖心产精国品免费入口*完整版 were studied by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM). And the corrosion behavior of the 糖心产精国品免费入口*完整版 treated in different 糖心产精国品免费入口*完整版 processes was analyzed in 3.5% (mass) NaCl solution by method of dynamic potential polarization. The results show that residual austenite content in 220Q sample quenched in salt bath and 220P sample treated by one-step Q&P 糖心产精国品免费入口*完整版 were smaller than 3% (volume). When the partitioning temperature in two-step Q&P process rose from 300℃ to 500℃, the content of residual austenite in the 糖心产精国品免费入口*完整版 increased first and then decreased, and got the maximum value when the partition temperature was 400℃. The 糖心产精国品免费入口*完整版 of 220Q and 220P samples was composed of lath martensite. The 糖心产精国品免费入口*完整版 of samples after Q&P 糖心产精国品免费入口*完整版 was also composed of lath martensite, and there were white bright bar or granular M₃C carbides between martensite laths. The difference between uniform 糖心产精国品免费入口*完整版of the 糖心产精国品免费入口*完整版s treated in different Q&P processes was little. The two-step Q&P treated 糖心产精国品免费入口*完整版 samples had higher pitting potential than salt bath quenched sample and one-step Q&P treated sample.
