“…In order to improve further the properties (mechanical and tribological) of electroless Ni-P coatings, numerous composite coatings based on electroless nickel-phosphorus matrix are investigated. By co-deposition of hard particles such as Al 2 O 3 , B 4 C, WC, SiC and SiO 2 [6][7][8][9][10][11][12][13], higher hardness and improved wear resistance are obtained, and, by incorporation of such soft particles as PTFE, graphite, MoS 2 , carbon nanotube, and hexagonal form of boron nitride (BN(h)) [14][15][16][17][18][19][20][21][22], the friction coefficient of electroless Ni-P coatings is modified. Vojtěch et al [6] investigated the sliding wear behavior of electroless Ni-P/Al 2 O 3 and Ni-P/SiC coatings deposited on an aluminium-silicon casting alloy.…”
