As with the nickel-copper alloys and high-nickel alloys, an alternative procedure employing a salt bath and Formula 8, with 10 g/L (1 oz/gal) of ferric chloride added to the formula, effectively removes oxide from hot-rolled or annealed Inconel alloys 601 and 671 and from Incoloy alloys 804 and 903. If the oxide film cannot be readily removed by pickling directly in Formula 3, or if a fused-salt bath is not available, Formula 13 is a useful pretreatment. The work should be soaked for 1 to 2 h in Formula 13, removed, rinsed to remove all of the caustic solution, and pickled in Formula 3. On highly refractory oxides, it is sometimes necessary to repeat the cycle. Adding 7 to 10 g/L (0.9–1 oz/gal) of iron to Formula 3 decreases the danger of overpickling. This can be done conveniently by adding the proper weight of scrap iron to the bath when it is prepared. |

與銅鎳合金和高鎳合金一樣,在另一替代方案中,采用了鹽浴和配方8,配方中添加了10 g/L (1 oz/gal) 的氯化亞鐵。這種方案可以有效地去除熱軋或退火鉻鎳鐵合金601、607和耐熱鎳鉻鐵合金804、903的氧化物。 如果使用配方3進行酸洗不容易去除氧化膜,或者不能進行熔浴,配方13可以進行有效的預處理。工件必須浸泡在配方13中,然后消除、洗掉所有的腐蝕性液體,然后用配方3進行酸洗。對于高度耐火的氧化物,有時必須重復上述循環(huán)步驟。在配方3中添加7-10 g/L (0.9–1 oz/gal)的鐵,可以減少過度酸洗的危險。只需要再配置鹽浴液時,添加合適重量的鐵屑即可避免過度酸洗,操作非常方便。 |
