1. The overlay chemical composition is the key
The main ingredients of Wodon plates are C(%) :3.0-5.0 and Cr(%):25-40. This chemical proportion results in a large amount of Cr7C3 chrome carbide hard particles. The micro-hardness (up to HV1800) of these particles throughout the layer will guarantee a super wear resistant surface.
Test equipment: Quartz sand rubber wheel abrasion test machine.
Conditions: Choosing same dimension specimens for different materials and wear plate producers, and put them under the same wearing working conditions in our testing equipment.
45 minutes for each specimen
Results: The test results show that the life span of Wodon wear plate is 2.5 times higher than domestic wear plates and 1.5 times than imported ones.
2. Chromium carbide microstructure
The wear resistance of wear plate depends mostly on the hardness, shape, size, amount and distribution of the chromium carbide hard particles.
As you can check on the picture, the carbide (Cr7C3) volume fraction on the microstructure is above 50%.
3. Bonding strength between the overlay and base plate.
The overlay and base plate are very well bonding. The overlay will penetrate into base plate about 0.8mm-1.8mm, reaching up to 350Mpa in our tests.
