Chromium boron alloy

Product Character Chromium boron alloy products are mostly in the form of gray/gray black powder, block or sintered body, with high temperature resistance, high hardness, corrosion resistance and good thermal conductivity. They are typical “high-performance hard functional materials” in the industrial field, widely replacing traditional wear-resistant and high-temperature resistant materials.   2.Specification Chromium boron alloy

Their core application scenarios can be divided into the following categories based on material form and functional requirements Surface protection field 1.Strengthening of mechanical transmission components:For wear prone components such as gears, bearings, and rollers, chromium boron coatings can be prepared using plasma cladding, laser cladding, or thermal spraying techniques, which can increase the surface hardness to HV 2500 or higher and improve wear resistance by 5-8 times compared to untreated components. 2.Chemical equipment anti-corrosion protection:Chromium boron compounds (such as CrB ₂) have excellent acid and alkali corrosion resistance, especially outstanding stability against highly corrosive media such as hydrochloric acid and sulfuric acid. 3.Mold surface strengthening:Chromium boron coating can be customized and optimized to meet the different needs of cold and hot work molds Hard materials field 1.Modification of cutting tools:Adding 5% -10% CrB ₂ to high-speed steel or hard alloy cutting tools can significantly improve their red hardness 2.Manufacturing of wear-resistant structural components:Chromium boron based wear-resistant parts prepared by powder metallurgy technology High temperature and extreme environmental fields Aerospace high-temperature components:Chromium boron coating can serve as a secondary protective layer in aircraft engine turbine blades and spacecraft thermal protection systems, and work synergistically with ceramic based composite materials
