Zirconium is an active metal with a great affinity for oxygen. The excellent corrosion resistance of the oxide film determines that it can be used in multiple corrosive environments.
First, industrial pure zirconium in all boiling concentrations of hydrochloric acid, corrosion rate is less than 0.025mm/ A.
Second, zirconium has excellent corrosion resistance in less than 70% sulfuric acid. In addition, because stainless steel and nickel alloy can not be used in high temperature, 20% sulfuric acid and boiling temperature below 40-60% sulfuric acid range, zirconium in sulfuric acid environment has an irreplaceable role.
Three, below 200℃, not more than 90% of nitric acid, zirconium has good corrosion resistance. However, attention should be paid to the stress corrosion cracking sensitivity of zirconium in nitric acid.
Zirconium is resistant to corrosion at all concentrations, even in boiling caustic solutions. The corrosion resistance is higher than that of tantalum, niobium and titanium.
Coating target material is a sputtering source that forms various functional films on the substrate by magnetron sputtering, multi-arc ion plating or other coating systems under appropriate technological conditions. To put it simply, the target material is the target material bombarded by high speed charged particles. In high-energy laser weapons, different power densities, different output waveforms and different wavelengths of laser interact with different targets, which will produce different killing and destruction effects. For example: evaporation magnetron sputtering coating is heating evaporation coating, aluminum film, etc. Replace different target materials (such as aluminum, copper, stainless steel, titanium, nickel target, etc.), you can get different film system (such as superhard, wear-resistant, anti-corrosion alloy film, etc.).
