Structure, thermal stability and mechanical properties of electroless Ni–P–W alloy coatings during cycle test

Mechanical properties and deformation behavior of amorphous nickel-phosphorous films measured by nanoindentation test

“…[18,19] However, only the hardness and elastic modulus of electroless plated Ni-P films have been obtained with this test. [7,8] These basic experimental data do not sufficiently represent the mechanical stability or failure model of the Ni-P films in practical applications. Analyses of the mechanical behaviors of the films relating to the deformation mechanism need to be further performed.…”

“…[4,5,6] To enhance further the mechanical properties and application variety of the coatings, especially at elevated temperatures, transition metals like tungsten and cobalt have been incorporated in the Ni-P films, and the mechanical properties of these films have been reported. [7,8] Generally, the Ni-P films with high P contents have an amorphous structure, [1][2][3][4][5][6][7][8] and amorphous materials are observed to exhibit better mechanical properties than crystalline ones because ductile deformation accounting for dislocation activity (formation and sliding) is no longer valid for amorphous structures. [9][10][11][12] However, the deformation mechanism based on bulk metallic glasses has been primarily investigated.…”

Characteristics of bulk liquid undercooling and crystallization behaviors of jet electrodeposition Ni–W–P alloy

“…Much work has been carried out on its corrosion behavior, wear behavior, microstructure, phase transformation, thermal stability, composition, microhardness and preparation of Ni-W-P alloys. [7][8][9][10][11][12][13][14][15][16][17][18][19] However, study on the degree of undercooling of Ni-W-P ternary alloys has not been concerned more, despite that undercooling is a native characteristic for alloy during solidification and a deep knowledge of undercooling of Ni-W-P alloy will help to control the metastable formation, grain refinement and composition homogenization to optimize the properties of Ni-W-P ternary alloy for engineering application.…”

Friction Performance Optimization of Chemically Deposited Ni-P-W Coating Using Taguchi Method

“…So the research could be extended for the ternary Ni-P-M alloy where the M is the transition metal. Addition of a third element into the binary electroless nickel to form a ternary alloy coating such as Ni-Cu-P [17], Ni-P-TiO 2 [18], Ni-W-P [19][20][21][22][23] has been studied.…”
