Progress of electroless amorphous and nano alloy deposition: a review – Part 2

Electroless Metallization of the Elements: Survey and Progress

“…In addition to EL baths, various examples of conventional applications of EL Ni and its alloys ( e.g ., Mo, W, Re) that exploit enhanced wear resistance, hardness, corrosion resistance, and ferromagnetic properties have been described previously in this article (note, e.g ., Molybdenum and Tungsten section and Rhenium section) and in numerous reviews. ,,,,,,− Likewise, examples have been described elsewhere in this article or others for EL Ni as a substrate for diffusion barriers ( e.g ., Molybdenum and Tungsten section), ,, Electroless Nickel Immersion Gold (ENIG) ( e.g ., Gold section), ,− Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG) ( e.g ., Palladium section), ,, and EMI shielding ,,− and will not be discussed here. The use of EL Ni processes for the fabrication of ultrablack films for optical applications has also been reviewed .…”

“…EL processes involving the Group 8 elements are dominated by those for iron and its alloys. 248 Although elemental iron possesses a lower catalytic activity and is more difficult to reduce than more noble metals, plating can occur via both galvanic deposition and conventional EL plating routes. However, the nature and quantity of the reducing agent and plating temperature are critically important in controlling deposition rate and film morphology.…”

Pt-based structured catalysts on metallic supports synthesized by electroless plating deposition for toluene complete oxidation

“…Electroless plating deposition (EPD) is an autocatalytic method in which the reduction of the metallic ions in the solution and the film deposition on the substrate can be carried out though the oxidation of the reducing agent present in the solution itself [24]. The electroless coating process has gained wide acceptance in the market due to the coatings' excellent corrosion and wear resistance properties [25,26]. Recently electroless nickel nanosheets on carbonaceous materials as supercapacitor electrode [27,28], and electroless palladium nano-scale layers on porous materials for hydrogen membrane separation [29,30] Ultrasonic vibration test Bending fastness test Tearing fastness test 200 no weight loss no surface cracking no surface peeling 350 no weight loss no surface cracking no surface peeling 450 no weight loss no surface cracking no surface peeling 600 no weight loss no surface cracking slight surface peeling metallic structured substrate was achieved by using this new technique of EPD.…”
