摘要
电铸属于现代首饰制作的生产工艺之一,而电流密度是影响电铸过程的主要因素,文章通过改变电铸的电流密度来研究其对绒沙铜电铸层的形貌、铸层的厚度均匀性以及上铸速度的影响。结果表明,电流密度较小时,可得到适当的细化绒沙晶粒和较为均匀的边角厚度,但增大电流密度有利于提高上铸速度,所以电铸过程应控制适当的电流密度,而当电流密度为2A·dm-2可获得较好的综合性能。
Electroforming is a technology of modern jewelry manufacture. As current density is the main influencing fator of electroforming process, the influence of electroforming current density on morphology and thickness of electroforming deposits、speed of electroforming were studied in this paper. As a result, small grains and uniform thickness of border were obtained by small current density, furthermore, electroforming can be speed up by increasing the current density. So there should be a suitable current density, and 2 A·dm-2 was thought as a batter one to obtain integrated performance.
