化学沉积镍磷合金是一种发展迅速、广泛应用的表面技术,用于模具的表面强化,具有极好的效果。这归结于镍磷合金沉积层具有以下特点。 (1)镍磷合金的沉积过程,仅依靠零件与溶液接触,毋需辅助阳极,无尖角电流密度增大现象,边缘突出部位不会过份增厚。能依照基体的外形轮廓均匀沉积。因具有仿型性,故适用于形状复杂的零件。 Chemical deposition of nickel-phosphorus alloy is a rapidly growing, widely used surface technology for the mold surface hardening, with excellent results. This is due to the following features of Ni-P alloy deposits. (1) Nickel-phosphorus alloy deposition process, only rely on parts and solution contact, without auxiliary anode, no sharp current density increases, the edge of the prominent parts will not be too thick. In accordance with the outline of the substrate contour uniform deposition. Due to the imitation, it is suitable for complex shape parts.
