在电化学领域中,超声学已有数种应用。超声波对电镀技术中电沉积过程的影响,虽不久前才开始,但从有些进行过的工作表明,这个方向大有可为。因此,超声电镀目前已被人们所重视和应用。其主要有如下原因:1.在超声场里金属电沉积速度可以大大地加速,其加速过程的本质是依靠采用升高电流密度和增高输出电流。若升高同样的电流密度而槽里没有超声波作用时,则其沉积质量就不好。如用硫酸溶液在超声场中进行电沉积时,电流密度可达到140安/分米~2时也可获得密实的细晶粒,且与基体金属结合的镀层是良好的,
In the field of electrochemistry, there are several applications of ultrasound. The influence of ultrasonic waves on the electrodeposition process in electroplating technology, though not long ago, started, but the work done from some shows that there is a real potential in this direction. Therefore, ultrasonic plating has been valued and applied by people. The main reasons are as follows: 1. In the ultrasonic field metal electrodeposition speed can be greatly accelerated, the essence of its acceleration process is to rely on the use of increased current density and increase the output current. If the same current density is raised without any ultrasonic action in the grooves, the deposition quality is not good. Such as sulfuric acid solution in the ultrasonic field electrodeposition, the current density can reach 140A / dm ~ 2 can also get dense fine grain, and with the base metal coating is good,
