MgZrO3 26Ni 7Cr 2Al Powder Description:
MgZrO3 26Ni 7Cr 2Al Powder is a mixture of magnesium zirconate and nickel-chromium-aluminum alloy powders, specifically formulated for use as an intermediate thermal spray coating in a three-layer, quasi-graded coating system. This system consists of a nickel-chromium alloy bond coat at the base and a magnesium-zirconate ceramic top coat. The intermediate layer created by MgZrO3 26Ni 7Cr 2Al Powder features a coefficient of expansion that effectively bridges the metallic bond coat and the ceramic top layer, distributing thermal stresses evenly throughout the coating system. This stress distribution improves resistance to spalling and other thermal shock effects, making it an ideal choice for thermal barrier coatings in high-temperature applications.
