Description
CCO, or chromium carbide overlay, only contains chromium-rich
carbides. Overlays can also be of the complex carbide type. In
these products other alloys such as Nb, Mo, V and W are added to
the chromium carbide.
Complex carbides are usually a preferred choice in hot wear
situations since they can maintain full wear resistance in
temperatures up to 600 ℃(1100℉). As complex carbides typically give 3-5 times longer service ife
compared to CCO, they are also suitable if the thickness of the
overlay is restricted.
High-performance overlay plates exposed to more than moderate
impact forces can use an alloy containing ultra-fine borocarbides.
These borocarbides can have a grain size as low as 500 nm, which is
approximately 200 times finer than traditional chromium or complex
carbides.
In the literature and by different manufacturers, overlay plate is
also caled carbide plate, chrome overlay steel, chrome overay plate
or hardfacing plate.

Advantages
1, high wear resistance
Carbon content in the chemical composition of the alloy layer of 4
~ 6%, the chromium content up to 25 ~ 30%, the microstructure of
Cr7C3 carbide volume fraction of 45% or more, the macro hardness
HRC56-62, the hardness of chromium carbide is HV1400 ~ 1800, higher
than the hardness of sand quartz in HV800 ~ 1200.Because the
carbide into vertical distribution in the direction of wear, even
compared with the same composition and hardness of casting alloy,
wear-resisting performance is more than double.
2, good resistance to impact
The ground floor of the wear-resistant composite plate is low
carbon steel or low alloy.Ductile material such as stainless steel,
and demonstrate the superiority of bimetal, wear-resisting layer of
abrasion resistance of medium wear and substrate under medium load,
thus has a good resistance to impact.Can withstand conveying system
under high head hopper and other impact and abrasion.
3, good heat resistance
Wear-resisting layer is recommended to use under the working
condition of 600 ºC or less use, if adding vanadium alloy layer,
such as molybdenum alloy, can withstand the high temperature of 800
ºC or less wear and tear.Recommended temperature is as follows:
ordinary carbon steel substrate recommended is not higher than 380
ºC condition of use;Low alloy heat-resistant steel plate (15 crmo,
12 cr1mov, etc.) recommended base plate is not higher than 540 ºC
condition of use;Heat resistant stainless steel substrates
recommend used at not higher than 800 ºC condition.
4, good corrosion resistance, wear resistance of composite steel
plate containing high percentage of chromium metal alloy layer, so
have ability to rust and corrosion.Used for coal cylinder and
hopper, etc can be done to prevent caking coal.
Application of Chromium Carbide Overlay Plate
Chromium Carbide Overlay (CCO) plates find application in various industries and equipment that experience high levels of wear. Some common applications of CCO plates include:
