我所研制成功并投入应用的涂镀液已有四种镍涂镀液和两种铜涂镀液。它们的牌号是:特殊镍TDY101、快速镍TDY102、低应力镍TDY103、镍钨合金TDY104、快速铜TDY401和碱铜TDY403。在机械维修部门中,用途较广和用量较大的涂镀液为:快速镍TDY102、特殊镍TDY101和碱铜TDY403。一、涂镀层的性能 1.涂镀层与基体金属的结合强度涂镀层与基体金属的牢固结合,是涂镀工艺具有使用价值的基础。由于采用专门的溶液对金属表面进行电-化学清洗和活化,涂镀液中的金属有机络合物具有较大的阴极极化作用,以及涂镀操作时阳极包套与工件表面接触(有相对运动),涂镀层与基体金属之间具有良好的结合强度。涂镀层与基体金属间的结合强度,尚未
I have developed and put into use the coating has four kinds of nickel plating solution and two kinds of copper coating solution. Their grades are: special nickel TDY101, fast nickel TDY102, low-stress nickel TDY103, nickel-tungsten alloy TDY104, fast copper TDY401 and alkaline copper TDY403. In the mechanical maintenance sector, a wider range of applications and greater amount of coating solution: fast nickel TDY102, special nickel TDY101 and copper TDY403. First, the performance of the coating 1. Coating and the base metal bonding strength The coating layer and the base metal firmly integrated, is the coating process has the basis for the use value. Due to the electro-chemical cleaning and activation of the metal surface with a special solution, the metal-organic complex in the plating solution has a greater cathodic polarization and the anode cladding contacts the surface of the workpiece during the coating operation Sports), coating layer and the base metal with good bonding strength. Coating coating and the bonding strength between the substrate metal, yet
