NiCrAlMoFe Powder Description:
NiCrAlMoFe Powder is a stainless composite powder comprising nickel, chromium, molybdenum, and aluminum, specifically designed for thermal spray applications. Nickel and chromium enhance resistance to oxidation and high-temperature corrosion, while molybdenum provides scuff and sliding wear resistance. The inclusion of aluminum, which promotes oxidation resistance and reacts exothermically with nickel during spraying, ensures excellent bond strength and interparticle bonding. This powder also contains boron and silicon, which improve overall hardness through the formation of hard precipitates and contribute to its self-fluxing capability and enhanced abrasive wear resistance. NiCrAlMoFe Powder produces hard, durable coatings that can be applied thickly without cracking or delamination and can be ground to achieve very fine finishes.

NiCrAlMoFe Powder FAQ:
Q1: How does NiCrAlMoFe Powder enhance wear resistance?
A1: The powder includes molybdenum, which provides scuff and sliding wear resistance, as well as boron and silicon that form hard precipitates of nickel and chromium borides and silicides in the coating, enhancing its overall hardness and abrasive wear resistance.
Q2: Can NiCrAlMoFe Powder be used for thick coatings?
A2: Yes, NiCrAlMoFe Powder can be applied in thick layers without cracking or delamination, even when using combustion powder Thermospray. This property ensures robust and durable coatings suitable for various industrial applications.
Q3: What are the benefits of aluminum in NiCrAlMoFe Powder?
A3: Aluminum in NiCrAlMoFe Powder promotes oxidation resistance and, in combination with nickel, produces an exothermic reaction during spraying. This reaction leads to very good bond strength and interparticle bonding, ensuring strong and durable coatings.
