Question

Boundary layers formed by chemical adsorption using additives are also called as friction modifiers.

(a) True

(b) False

The question was posed to me in my homework.

I need to ask this question from Friction and Lubrication in Metal Forming in section Types of Die & Metal Forming Processes of Casting-Forming-Welding II

Answer 1

The correct answer is:

(a) True

In metal forming, boundary layers formed by chemical adsorption using additives can indeed act as friction modifiers. These additives, which adsorb onto the surface of the metal, can reduce friction during the forming process, improving the flow of materials and reducing wear and tear on the die.
