CERCARB 25TM is a ceramic material that has excellent wear resistance, while carbide is a compound that also has good wear resistance properties. However, CERCARB 25TM has some advantages over carbide when it comes to wear resistance against steel.
One of the reasons why CERCARB 25TM wears better than carbide against steel is that it has a high hardness and great toughness. Hardness is the ability of a material to resist surface indentation, while toughness is the ability to resist cracking or fracturing. CERCARB 25TM has a high hardness and toughness, which means it can withstand abrasion and impact without cracking or breaking, while carbide can be brittle and may crack under certain conditions.
Another reason why CERCARB 25TM wears better than carbide against steel is that it has a lower coefficient of friction. Coefficient of friction is the ratio of the force required to move an object over a surface to the normal force pressing the two surfaces together. A lower coefficient of friction means less energy is required to move an object over the surface, which reduces the wear and tear on the material. CERCARB 25TM has a lower coefficient of friction than carbide, which means it experiences less wear when in contact with steel.
Lastly, CERCARB 25TM has a higher chemical stability compared to carbide. When in contact with steel, carbide may undergo chemical reactions and degrade, leading to wear and corrosion. CERCARB 25TM is resistant to chemical reactions with steel and has a high corrosion resistance, which makes it more durable and wear-resistant in these types of environments.
Overall, the combination of high hardness, toughness, low coefficient of friction, and chemical stability make CERCARB 25TM a superior material for wear resistance against steel when compared to carbide.
