炉管服役过程的时效与渗碳导致大量碳化物的析出，其数量、大小与形态取决于服役温度和时间。
Aging and carburization during the service produced precipitation of carbides, the amount, size and forms of which depended on the service time and working temperature.
经该工艺处理后渗层可获得弥散碳化物，其性能大大优于常规渗碳。
After being treated with this technique, the disperse spheroidal carbide can be obtained in the carburizing case which is superior to that by normal carburizing in properties.
通过观察球光体表面或碳化物的增加的数目在球化处理材料方面，在视力上发现可能的表面渗碳。
Possible surface carburization may be detected optically in spheroidized materials by observation of surface pearlite or an increased number of carbide spheroids.
