七、氧化处理这里低以碳钢零件为例,说明氧化处理的具体操作方法:零件经过上列处理以后,稍稍抖去水分,立即放入药水锅內。篮子的吊钩掛在吊架上,使篮底不要与锅底接触。零件表层,至少要低于液面15公厘。液面要低于锅口30公厘,以免药液在温度过高时沸腾溢出。零件和零件之间,不能互相密接,不然就会使密接部分色泽不匀。零件放入药水锅时,溶液温度最好在135～140℃范围內,使氧化膜的晶苞较稀疏地生成,这就能达到较大的晶体,形成较厚的氧化膜。零件在溶液内放置3～5分钟后,立即把篮子从药水锅中取出,移入冷水槽中摇动洗刷。为了节
Seven, oxidation Here low carbon steel parts, for example, explain the specific method of oxidation treatment: Parts after the above treatment, a little shake the water, immediately into the pot. Hook the basket hanging on the hanger, so that the bottom of the basket with no contact with the bottom. Parts of the surface, at least below the liquid level 15 mm. The liquid level should be 30mm lower than the pot mouth, so that the liquid will not overflow when the temperature is too high. Between parts and parts, can not be close to each other, otherwise it will close the part of uneven color. Parts into the pot, the solution temperature is best in the range of 135 ~ 140 ℃, so that oxide film is more sparsely formed, which can achieve larger crystals, the formation of thicker oxide film. After the parts have been left in solution for 3 to 5 minutes, remove the basket from the pot and move it into the cold water tank to shake it. For the festival
