在不使用电能的情况下,化学镀依靠含有还原剂的水溶液中金属离子的催化还原,从而实现金属的沉积.其成功与否,很大程度上取决于温度的维护.温度升高,沉积速度加快,因此,应当避免热量散失到周围环境中.本丈估算了包裹不同隔热材料的化学镀镍液的散热量.结果表明,采用棉花作为隔热材料,热损失可降至最低,从而提高并维持一定的沉积速率.
Electroless plating depends on the catalytic reduction of a metal ion in an aqueous solution containing a reducing agent and the subsequent deposition of the metal without the use of electrical energy.Its success depends to a great degree on the maintenance of temperature.Increase in temperature increases the rate of deposition and hence the heat loss to the surroundings should be prevented.In this paper,the amount of heat lost from the electroless nickel bath with different insulating materials was estimated,it becomes evident from the results that the heat loss to the surroundings is minimided when cotton is used as insulating material and it enhances and maintains the rate of deposition.
