The relationship between the friction mechanism and the quality of zirconia ceramics
As a zirconia ceramic manufacturer, we require the quality of the product to be higher and better, so that it will have a certain credibility and increase its own benefits faster, so when preparing the product, there is a certain friction, which is what we call the friction theory, and the following will introduce the friction theory in detail
Adhesion theory: The theory believes that under a certain pressure, zirconia ceramics will produce instantaneous high temperatures when they are dry and rubbing, sometimes even more than 1000C°, which will cause zirconia ceramics to produce a certain degree of plastic deformation, and the two objects will be adhesed. The friction is the jumping process of alternating adhesion and slippage, which will make the movement resisted, that is, equal to the sum of the resistance when each adhesive point is sheared.
Mechanical theory: under the influence of great pressure, friction zirconia ceramics are in a mixed state of elasticity and plasticity when they are in contact, and the surfaces are meshed with each other and in contact, and when they slide relatively, the meshing points of each other are sheared, thus constituting the resistance of relative motion.
Friction is the resistance at which the various meshing points are sheared. At the same time, molecular gravity will be generated at the contact site of zirconia ceramics, as if a load is applied, so when the friction couples move relative to each other, on the one hand, they must overcome the mechanical meshing, and on the other hand, they must overcome the molecular gravity, which causes the wear of the material.
It can be seen from the above that the friction theory of zirconia ceramics includes two aspects, namely adhesion theory and adhesion theory.
Zirconia ceramics have high hardness, the brittleness of the material is large, and it is easy to chipping and chipping during processing. Generally, the processed ceramic parts are processed by a special ceramic engraving machine, which can effectively reduce the cost and achieve high-precision machining. Xin Tenghui CNC has developed a ceramic engraving and milling machine for ceramic processing, with good protection performance and high processing accuracy. The ceramic engraving and milling machine strengthens the rigidity of the machine tool, and the vibration generated during processing can be reduced to a minimum, ensuring the accuracy while also improving the processing efficiency, and the protective performance is strengthened for the ceramic powder, which can completely eliminate the damage of the powder to the machine tool. Xin Tenghui CNC can also provide ceramic processing technology, with a skilled CNC machining, grinding team, precision parts research and development custom processing, etc.
