分别在垂直和平行磁场环境下电沉积镍,利用XRD和SEM 研究了电流密度、磁场强度、磁场方向、超声强度对镍晶镀层织构,以及磁场强度对镀层表面形貌的影响作用,并对其影响机理进行了分析。结果表明:增大电流密度对(200)晶面取向具有促进作用,随着电流密度的增大,晶面织构由以(111)为主变为以(200)为主;磁场强度增加会促使镀层织构(111)晶面取向增强,平行磁场相较于垂直磁场更有利于晶粒生长;超声作用会使晶粒由择优取向变为随机取向;此外,施加磁场作用后,晶粒尺寸随磁感应强度增加而减小,表面更加均匀。

Electrodeposited nickel under the perpendicular and parallel magnetic field environment, texted the effects of current density, magnetic field strength, direction of the magnetic field and ultrasonic intensity on the nickel crystal coating texture and the effect of the magnetic field strength on the coating surface morphology by using XRD and SEM, and analyzed the impact mechanism. Test results show that improving the current density will promote the(200)crystal orientation, as the increase of the current density, the texture orientation changes from (111)to(200); Magnetic field strength will enhance coating texture(111)crystal surface, parallel magnetic field compares more conducive to grain growth with the vertical magnetic field; Ultrasonic intensity will make grain from preferred orientation to random orientation; With the increase of the magnetic induction, the grain size decreases and the surface is more uniform.
