What is a metal’s ability to withstand wear, abrasion and penetration called? Correct Answer Hardness

Explanation:

Hardness:

  • Hardness is a measure of a metal's ability to withstand scratching, wear, abrasion, and penetration.
  • The maximum hardness of steel is a function of its Carbon content.
  • It increases as the percentage of carbon increases.

Mechanical properties of metal:

Ductility

A metal is said to be ductile when it can be drawn out into wires under tension without rupture. Wire drawing depends upon the ductility of a metal. A ductile metal must be both strong and plastic. Copper and aluminium are good examples of ductile metals.

Malleability

Malleability is the property of a metal by which it can Be extended in any direction by hammering, rolling, etc. without causing rupture. Lead is an example of a malleable metal. 

Hardness

Hardness is a measure of a metal's ability to withstand scratching, wear, and abrasion, indentation by harder bodies.

Brittleness

Brittleness is the property of a metal which permits no permanent distortion before breaking. Cast iron is an example of a brittle metal which will break rather than bend under shock or impact.

Toughness

Toughness is the property of a metal to withstand shock or impact. Toughness is the property opposite to brittleness. Wrought iron is an example of tough metal.

Tenacity 

The tenacity of a metal is its ability to resist the effect of tensile forces without rupturing. Mild steel, Wrought Iron, and copper are some examples of tenacious metals.

Elasticity 

The elasticity of a metal is its power of returning to its original shape after the applied force is released. Properly heat-treated spring is a good example of elasticity.

Resistivity

It is the property of a substance due to which it opposes the flow of the electric current.

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?
