Friction theory of zirconia toughened alumina

Friction theory of zirconia toughened alumina

With the development of science and technology, the quality requirements of zirconia toughened alumina products are higher and better, so the products have certain friction during preparation, which is what we call friction theory. The following will introduce the friction theory in detail:

1. Zirconia toughened alumina adhesion theory:

The adhesion theory of zirconia toughened alumina believes that under a certain pressure, when zirconia toughened alumina is dry rubbed, it will generate instantaneous high temperature, sometimes even more than 1000e, which will cause zirconia toughened alumina to produce a certain degree of damage. Plastic deformation, the two objects will stick together. Its friction is a pulsating process in which sticking and slipping alternately occur, and this process will make the movement subject to resistance, which is equal to the sum of the resistances when each sticking point is sheared off.

2. Mechanical theory of zirconia toughening alumina:

Under the influence of great pressure, the friction zirconia toughened alumina is in a mixed state of elasticity and plasticity, and the surfaces mesh with each other and contact each other, and when they slide relatively, the meshing points are sheared, so resistance to relative motion.

Zirconia toughened alumina friction is the resistance when each meshing point is sheared. At the same time, molecular attraction will be generated at the contact part of zirconia toughened alumina, just like applying a load, so when the friction couple moves relative to each other, on the one hand, it must overcome the mechanical mutual meshing, and on the other hand, it must overcome the molecular attraction. This causes wear of the material.
