Preparation of nickel-coated graphite by electroless plating under mechanical or ultrasonic agitation

A Study on Electroless Deposition of Nickel on Nano Alumina Powder Under Different Sensitization Conditions

“…Initially, the powder was treated with acetone using Ultrasonic cleaner and later on with different chemicals to complete the pretreatment process. Xu et al, reported Ultrasonic agitation promotes better nucleation and deposition of nickel than mechanical agitation in case of nickel-coated graphite [10]. The detailed description of the chemicals and their purposes used for experimentation are mentioned in the Table 2.…”

Graphite and Nickel Containing Tin Bronze-Steel Bimetals as Lead Free Bearing Materials

“…By contrast, the hardness of the no Ni containing composite with 10 vol% graphite is 35.0 HB, lower than that of the Ni containing composite with same graphite content. The addition of Ni can improve the interface between graphite and CuSn10 matrix, which leads to enhancement of hardness of composites 11,14 . The hardness of CuSn10Pb10 alloy is 42.4 HB, lower than the Ni containing composite with 5 vol% graphite and higher than the Ni containing composites with 8 vol%, 10 vol% and 12 vol% graphite.…”

“…But the interface binding between graphite and copper matrix is weak due to their incompatibility, which decreases the mechanical and tribological performance of the composites [2][3][4][5][6][7] . Modification techniques of graphite such as: Cu electroplating 8,9 , Cu electroless plating 10,11 , Ni electroplating 12 and Ni electroless plating [13][14][15] are effective routes to improve the interface. Nevertheless, these modification techniques are complicated, expensive and cannot be employed in large scale production.…”

Fabrication and electromagnetic properties of novel FeNi alloy-coated flake graphite prepared by electroless plating

“…Zhou et al [16] prepared Co-coated flaky carbonyl iron particles by electroless plating and investigated electromagnetic properties after heat treatment. Xu and coworkers [17] synthesized Ni-coated graphite powders by electroless plating. They discussed the effect of different agitation on the formation and morphologies of coating.…”
