ZrO2 7.5Y2O3 4Polymer Powder Description:
MgZrO3 35NiCr Powder is a composite of magnesium zirconate and nickel-chromium alloy powders, specially formulated for use as an intermediate thermal spray coating in a three-layer, quasi-graded coating system. This system comprises an underlying bond coat of nickel-chromium alloy, an intermediate layer of MgZrO3 35NiCr, and a top layer of magnesium-zirconate ceramic. The intermediate layer provided by MgZrO3 35NiCr Powder has a coefficient of expansion that acts as a bridge between the metallic bond coat and the ceramic top coat, effectively distributing thermal stresses across the coating system. This results in a robust thermal barrier coating that minimizes spalling and thermal shock effects, ensuring durability and performance in high-temperature environments.
