Process Overview TRIMAY WEAR PLATE is a high Chromium Carbide containing ferrous alloys deposited by a patented process on a high grade mild steel plate. The relatively rapid cooling rate obtained with this process produces a very fine structure consisting of Chromium Carbide having an acicular morphology in the matrix which is tough and of medium hardness. Various grades are made with differing proportions of high carbides in the tough matrix to suit individual applications. The overlaid deposit is fully fused to the ductile backing plate, thereby, preventing failure due to fracture or de-lamination. The application procedure is what makes our plate unique. The process has the advantage of making perfect fusion of the alloyed layer with the host material. At the same time, the effect of dilution is reduced as much of the heat generated is used in the melting of the powder. The final result is that the deposited metal is not contaminated by the inferior metal of the host material, such as happens with other known processes. This also means that the base material retains its mechanical strength, thereby allowing it to be used as a structural element. Fusion takes place under a thick flux cover, thereby virtually eliminating oxide formation and gas pick-up, resulting in an inclusion free deposit. It also produces a relatively smooth weld bead, creating a flat surface across the plate. The result is an extremely low coefficient of friction when compared to all other brands of wear plate. The actual composition of TRIMAY’s range of products can be adjusted much more freely than is possible with processes dependent on commercially available welding rods, wire, etc. This enables us to produce a range of compositions to suit specific applications.  |
