Products Description
Ni95Al5 thermal spray wire plays an important role in the aerospace field, and its excellent high-temperature performance and corrosion resistance make it an ideal choice for protecting critical components. This coating material based on nickel aluminum alloy can provide reliable protection under extreme conditions, protecting aerospace equipment from high temperature, corrosion, and oxidation, thereby extending its service life and improving performance.
In aerospace applications, Ni95Al5 thermal spray wire is commonly used for surface coating of critical components such as turbines, jet engines, and turbine blades. These components are subjected to extreme temperatures and pressures during flight, thus requiring excellent high-temperature resistance and antioxidant capacity. The oxide layer formed by Ni95Al5 coating can effectively prevent further oxidation of the substrate, while providing good thermal isolation performance, which helps maintain the stable working temperature of the components.
In addition, the Ni95Al5 coating also has good adhesion and wear resistance, which can resist external environmental factors such as wind pressure, airflow, and mechanical vibration, ensuring the reliability and safety of aerospace equipment. Due to its chemical inertness, it can also perform well in extreme chemical environments, enhancing its applicability in the aerospace field.
