ASTM G65 chromium carbide overlay CCO wear resistant plates for engineering machinery

Chromium Carbide Overlay Wear Plates

Wodon wear plates are manufactured by welding one or multiple wear resistant layers on a medium or low carbon steel base plate.The overlay alloy has a high amount of chromium carbide hard particles which makes the plate have good wear and impact resistance. 

Overlay thickness range: 3-50mm

Standard thickness(mm): 3+3, 4+4, 5+5, 6+6, 8+6, 8+8, 10+6, 10+8, 10+10,

12+12, 12+17, 14+26, 12+32 etc

Wear plate size(mm): 1400*3000,  1400*3400,  1400*3500,

1500*3000,2000*3000,  2100*3500,

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.

Performance test:

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.
