涂镀是电化学沉积金属的一种特殊工艺形式。操作时,将专用电源的正负极分别接在涂镀笔和工件上,涂镀笔前装有石墨电极,电极外面包敷脱脂棉套,蘸上涂镀液后使其与工件接触并作相对运动。这时,涂镀液中的金属离子便在电场作用下,快速沉积在工件表面上,形成涂镀层。随着时间的延长即通过电量的增加,涂镀层逐渐变厚,从而达到保护、维修工件和改变其
Plating is a special form of electrochemically deposited metal. During operation, the positive and negative electrodes of the special power supply are respectively connected to the coating pen and the workpiece. The graphite electrode is coated before the coating pen and the absorbent cotton cover is coated on the outside of the electrode. After being dipped in the coating solution, movement. At this time, the coating solution of metal ions in the electric field, quickly deposited on the workpiece surface, the formation of coating. With the extension of time through the increase of electricity, coating gradually thickening, so as to protect, repair and change the workpiece
