采用固体渗碳虽然成本低、操作方便,但渗层深度较难控制。我们在固体渗碳箱上开一个φ13mm的洞,在装箱时将焊把的φ10mm 试棒从洞口装入渗碳箱中,使试棒靠近工件,洞的四周缝隙用黄泥或耐火泥封口。当估计渗碳层深度达到要求时,将试棒抽出淬入水中,打断试棒即可检测渗层深度。如深度不足还可以继续延长保温时间,估计合格时再
Although the use of solid carburizing low cost, easy operation, but difficult to control the depth of the infiltration layer. We open a φ13mm hole in the solid carburizing box, put the φ10mm test bar of the welding bar into the carburizing box from the hole when packing, so that the test bar is close to the workpiece, the hole around the hole is sealed with yellow mud or fireproof clay . When the estimated depth of carburizing layer to meet the requirements of the test rod out of quenching into the water, the test bar can be interrupted to detect the depth of the infiltration. If the depth can continue to extend the holding time, estimated to pass again
