摘 要:    研究了低温(~40 ℃)超声波化学镀镍层的初期析出行为、组织和相结构并与常规化学镀镍层进行了比较,结果表明低温超声波化学镀镍层细密均匀,而常规化学镀镍层晶粒粗大且呈不均匀状态,在镀层的横截面上有分层现象。 低温超声波化学镀镍层主要为非晶态, 夹有少量微晶, 而常规化学镀镍层则为典型的非晶态。

Abstract:Compared with common electroless nickel coatings, the primary stage deposition behaviour and microstructure of low temperature (~40 ℃)ultrasonic electroless nickel coatings were studied. The low temperature ultrasonic electroless nickel coating showed that fine grains well-distribute on the substrate surface, and granular ones in its cross section. The common electroless nickel coating observation showed that thick and big grains bad-distribute on the substrate surface, and a dim lamellar structure appears in its cross section. The majority of low temperature ulrtasonic electroless nickel coating is amorphous, but it is mixed with microlites. The common electroless nickel coating is typically amorphous.
