氰化分固体的、液体的和气体的三种,而以气体氰化为最好。但目前采用比較多的,还是固体氰化。这种氰化方法能够提高高速鋼刀具的使用寿命一般在1～2倍,高的可达5～10倍,同时还能够改善加工工件的表面光洁度。它不要求有特殊的设备,而且操作也简便。低温固体氰化法所用的氰化剂有两种成分,一种是含有促进剂的,一种是没有促进剂的。我們就是采用后面一种氰化剂,具体成分是:木炭 Cyanide sub-solid, liquid and gas three, while the gas cyanide is best. However, the current use of more, or solid cyanide. This method of cyanidation can improve the life of high-speed steel tools generally 1 to 2 times, up to 5 to 10 times higher, while also improving the surface finish of the workpiece. It does not require special equipment and it is easy to operate. Cyanide used in the low temperature solid cyanidation has two components, one containing a promoter and one without a promoter. We are using a behind a cyanide agent, the specific ingredients are: charcoal
