AMPERIT® MCrAlY - Thermal spray powder for hot gas corrosion resistant coatings

MCrAlY coatings are the key to the performance and reliability of highly stressed turbine parts. The M in MCrAlY stands for the base metal (usually nickel, cobalt or a combination of the two), which is alloyed with chromium, aluminum and yttrium. Cobalt and nickel are typically used as a base for the undercoating to make the metallic intermediate layer ductile. Aluminum and chromium form a stable oxide layer that protects coatings from oxidation. Yttrium enhances the bonding of this oxide layer.

CoNiCrAlY Powder
H.C. Starck markets its thermal spray powders under the AMPERIT® brand name. AMPERIT® MCrAlY powder is used as a coating to protect parts from oxidation. Moreover it is applied as a bond coat  for the thermal barrier coating (TBC) required by various aircraft and industrial gas turbine components (e.g. turbine blades and thrust chambers). In addition, the good wear resistance achieved by combining MCrAlY and aluminum oxide (Al2O3) make it well suited for furnace rollers in steel factories.

Developing prototypes

H.C. Starck’s small-scale atomization system provides a unique opportunity to produce test batches for our customers. With our expertise in application technology and materials, we have the tools to offer customized solutions – from thermal spray powders to the realization of comprehensive coating concepts. Long-term partnerships with OEMs (original equipment manufacturers) and manufacturers of spraying systems as well as joint research and development activities make H.C. Starck an experienced and reliable partner for your materials supply. We have the capacity and know-how to supply the turbine industry with a unique package of high-quality powders, technical support and material development according to our customers’ specifications.

Sustainable and secure raw materials supply

H.C. Starck’s raw material supply is founded on two pillars: the continuous expansion of our recycling activities and the fair, ethical and environmentally friendly procurement of raw materials. Our responsible supply chain management ensures the conflict-free origin of the primary raw materials we purchase. As a result of our sustainable procurement process, we have already been certified twice by the EICC as a “Conflict-Free Smelter.”

As a thermal spray powder manufacturer, our backwards integration of rhenium and tantalum containing MCrAlY powders and chemical overspray recycling put us in a unique position to offer exceptional supply security and quality.
