摘 要: 研究了低溫(~40 ℃)超聲波化學(xué)鍍鎳層的初期析出行為、組織和相結(jié)構(gòu)并與常規(guī)化學(xué)鍍鎳層進(jìn)行了比較,結(jié)果表明低溫超聲波化學(xué)鍍鎳層細(xì)密均勻,而常規(guī)化學(xué)鍍鎳層晶粒粗大且呈不均勻狀態(tài),在鍍層的橫截面上有分層現(xiàn)象。 低溫超聲波化學(xué)鍍鎳層主要為非晶態(tài), 夾有少量微晶, 而常規(guī)化學(xué)鍍鎳層則為典型的非晶態(tài)。

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.
