MgZrO3 26Ni 7Cr 2Al Powder Description:
MgZrO3 26Ni 7Cr 2Al Powder is a blend of magnesium zirconate and nickel-chromium-aluminum alloy powders, designed for use as an intermediate thermal spray coating in a three-layer, quasi-graded coating system. This system includes an underlying bond coat of nickel-chromium alloy and a top coat of magnesium-zirconate ceramic. The intermediate layer provided by MgZrO3 26Ni 7Cr 2Al Powder has a coefficient of expansion that bridges the metallic bond coat and the ceramic top coat, effectively distributing thermal stresses throughout the coating system. This distribution enhances resistance to spalling and other thermal shock effects, making it an excellent choice for thermal barrier coatings in high-temperature environments.
