Adhesion improvement of electroless plated Ni layer by ultrasonic agitation during zincating process

Grinding characteristics of micro-abrasive pellet tools fabricated by a LIGA-like process

“…2 mainly included three steps [13]: (1) micro-lithography that contains the design of the photo mask, resist coating, UV light exposure, and development, (2) electrolytic machining that make holes on substrates, and (3) micro-composite electroforming that deposits diamond particles (size of 4-6 mm) into the nickel matrix on substrates using the nickel sulfamate bath. Besides, the substrate surface needs a very good pretreatment and copper sputtering [13] or zincating [14] to enhance adhesion.…”

Deposition of Electroless (Ni-P-ZnO) Ternary Alloy for Adhesion Strength on Magnesium (AZ91) Alloy: Effect of Surfactant

“…The deposition, to a large extent, improves the mechanical and tribological properties of Ni-P coatings [1][2][3][4][5]. Such coatings with a high corrosion resistance, wear resistance, good adhesion properties and uniform coating thickness have found wide applications in the industries of aviation, aerospace, electronics, petroleum, chemistry, machinery, textiles and automotives [6,7].…”

Insight of the interface of electroless Ni–P/SiC composite coating on aluminium alloy, LM24

“…Zincating is the result of the electrochemical exchange reaction between zinc ions in the solution and the aluminium metal to deposit zinc crystallites at the expense of aluminium dissolution (etching) [9][10][11][12][13]. Several investigators developed and studied the zincating film and its distribution.…”

“…Several investigators developed and studied the zincating film and its distribution. Jin et al [11] studied the zincating process by employing ultrasonic technique which produces dense population of small Zn particles and increases the coverage of Zn intermediate layer. Sufficient nucleation of dense population of small Zn particles is required for the good adhesion of nickel deposit.…”
