Abstract
A blended flame spray powder composition is provided for use in producing a bonded wear resistant coating on an aluminum bronze substrate such as a glass mold part. The blended composition comprises a copper-base alloy mixed with a nickel-base alloy, the copper-base alloy powder comprising by weight about 5% to 15% aluminum, about 5% to 30% nickel, 0 to about 1% iron, about 0.1 to 1% silicon and the balance essentially copper. The nickel-base alloy powder comprises by weight 0 to about 0.5% carbon, 0 to about 1% manganese, 0 to about 21.5% chromium, 0 to about 7.5% iron, 0 to about 3.75% columbium, about 0.5% to 3% silicon, 0 to about 9% molybdenum, 0 to about 2% boron, 0 to about 2.5% phosphorus and the balance essentially nickel. The blending ratio of one powder to the other is such that a bonded coating produced therefrom on an aluminum bronze substrate, such as a glass mold part, contains at least about 9% copper and at least about 1.25% aluminum.
