Annealing process of Wear Resistant Plate
Nov 08, 2018

The chromium carbide Wear Resistant Plate has a very uniform permeable layer inside, which is usually made of medium carbon steel. The adhesion between the composite layer and the substrate is the largest, and the penetration diffusion is minimal. In the process of processing, this is more conducive to molding, especially the formation of complex shapes. Annealing is required during the forming process to improve the chemical properties of the sheet.


This helps the Wear Resistant Plate to achieve the desired results. Usually, annealing treatment can significantly improve the electrochemical performance of the alloy electrode. This is because annealing can reduce or even eliminate the LaNi3 phase, and annealing can also reduce macrosegregation to homogenize the internal components of the alloy. It is usually necessary to anneal for a longer period of time in order to obtain a uniform structure.


In general, three kinds of reactions usually occur during the annealing process of the Wear Resistant Plate: 1. The peritectic reaction causes the LaNi3 phase and the CaCu5 phase to undergo a peritectic reaction to form the A2B7 phase; 2. The loss of the A-terminal element is caused. The A2B7 phase is transformed into the CaCu5 phase; 3. The low temperature phase Ce2Ni7 phase in the A2B7 phase is converted into the high temperature phase Gd2Co7 phase.
