How does the amount of cobalt affect the wear of alloys?

How does the amount of cobalt affect the wear of alloys? Correct Answer High cobalt high wear

Higher cobalt concentration of about 13-17% results in 30-40% faster wear or the alloys. However, it provides better resistance to mechanical shock. The basic tungsten-carbide composition containing 6-8% cobalt is recommended for general wear applications.

Consider the following statements: 1. HSS tools wear very rapidly, whereas in cemented carbide tools, even though hardness is retained, crater wear can occur due to solid-state diffusion. 2. Cutting tools made of Super-HSS, also known as cobalt-based HSS, are made by adding 2% to 15% of cobalt which increases the cutting efficiency at heavier cuts by increasing the hot hardness and wear resistance. 3. Tools failure due to excessive stress can be minimized by providing small or negative rake angles on brittle tool materials, protecting tool tip by providing large side-cutting edge angles, and honing a narrow chamfer along the cutting edge. Which of the above statements are correct?
