摘要： Disclosed are electrolessly plated nickel coatings containing 0.5 to 3.0% by weight of phosphorus and 0.05 to 2.0% by weight of boron, coatings obtained by subjecting to heat treatment electrolessly plated nickel coatings containing 0.5 to 3.0% by weight of phosphorus and 0.05 to 2.0% by weight of boron and machine parts having sliding surfaces wherein at least the sliding surfaces are coated with the coatings. The coatings can be suitably provided on base materials composed of aluminum alloys or the like, show high hardness, high impact strength (high toughness) and improved lubricating characteristics such as sliding characteristics and, in addition, can be formed at a high rate.
