Sample Applications

Following is a list of some of the applications of our overlay and hardfacing technology.


Dozer Blade Liner Using RPM Chromium Carbide Overlay Plate Dozer Blade Liner
RPM's MK chrome carbide overlay makes excellent dozer blade liners. The hard, chromium carbide overlay polishes to a smooth surface that prevents material hang-up and allows material to be pushed faster than with other overlays.  The abrasion resistance ensures the blade has a long service life.

A dozer blade liner RPM installed in November, 1999 is still in operation today, more than ten years later, with over 61,000 hours of service! ... and is still going!

Bucket Liner Dragline and Other Bucket Liners
RPM offers reduced-weight overlay wear plate for loading applications such as dragline buckets. A variety of overlay combinations are available in wear plate as thin as ¼ inch. Our “stringer” bead overlay supports a better carbide structure than oscillated beads, therefore increasing resistance to abrasion and lengthening service life. RPM can design and install your bucket or dragline liner system or build to your specifications for install in the field.
