MgZrO3 35NiCr Powder Description:
MgZrO3 35NiCr Powder is a blend of magnesium zirconate and nickel-chromium alloy powders, specifically designed for use as an intermediate thermal spray coating in a three-layer, quasi-graded coating system. This system consists of an underlying bond coat of nickel-chromium alloy, an intermediate layer of MgZrO3 35NiCr, and a final top coat of magnesium-zirconate ceramic. The intermediate layer provided by MgZrO3 35NiCr 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 results in a highly resistant thermal barrier coating that minimizes spalling and thermal shock effects, ensuring durability and performance in high-temperature environments.
