Electroless nickel-boron coatings on metal carbides

Effect of Heat Treatments for Electroless Deposited Ni-B and Ni-W-B Coatings on 7075 Al Alloy

“…Heat treatment, the increase in the hardness of the coating enhances the plastic resistance of the deposit. Hence the friction coefficients and wear rates for heat-treated electroless Ni-B coatings are less when compared to as-plated specimens [14], [15]. Besides, heat treated Ni-B coatings exhibit spectacular adhesion on substrate [12].…”

Coating different thickness nickel–boron nanolayers onto boron carbide particles

“…XRD showed that the as-coated Ni-B is amorphous unless being heat treated. Giampaolo et al coated Ni-B on sintered metal carbide substrates using alkaline and acidic boron-containing baths [13]. Both methods produced continuous films with uniform thickness, with the acidic bath yielding higher coating rate.…”

PREPARATION AND CHARACTERIZATION OF ALKALINE ELECTROLESS Ni-B NANO DEPOSITION ON MILD STEEL IN THE PRESENCE OF AZADIRACHTA INDICA GUM

“…Nowadays researchers shift more attention towards Ni-B plating because of their widespread acceptance of Ni-P deposit 2,3 . In general, NaBH4 [4][5][6][7][8][9][10] or (CH3)2NHBH3 [11][12][13][14][15][16][17][18][19][20][21] were most commonly used as reducing agents for Ni-B plating. The reducing power of NaBH4 is much higher than that of (CH3)2NHBH3 and NaH2PO2.H2O.…”
