cobalt based Stellite 6 deposited on a steel substrate using plasma transferred arc (PTA) welding. The cast samples and the hypereutectic weld overlay samples were sectioned from worn plant components, and the Stellite 6 sample was sectioned from a bead on plate PTA deposit. The hypereutectic casting, Fig. 1, has a microstructure consisting

The results of the wear tests are compared to the wear of reference materials: steel Hardox 400, composite wear plate CDP 112 (Castolin Eutectic® Ltd.), and hardmetal VK15.
![[PDF] Welding processes for wear resistant overlays ...](/16f3wsv/391.jpg)
Abstract This paper presents a comprehensive survey of welding processes used to deposit wear resistant overlays. It is based on both literature review and research work performed at the Canadian Centre for Welding and Joining. The focus is on the two most popular material systems used for wear resistant overlays: nickelbase with the addition of tungsten carbide particles, and ironbase in ...
Fused Alloy plate is produced with a rich chromium carbide surface metallurgically bonded to an A36 mild steel base plate. With Fused Alloy plate, microstructure of the alloy influences our ability to provide the highest quality wear plate. We not only offer the highest percentage of chromium carbides, but also the hardest most evenly dispersed.
Galvanised Mild Steel Sheet, also known as plate, is ideal for quick and easy roofing solutions, offering large coverage combined with good protective qualities. Our Galvanised Steel Sheet is stocked in various thicknesses from 1mm thick to 3mm thick. We also stock a variety of sizes and offer a cutting service with up to UNLIMITED FREE cuts ...
where standard wear plate and Plasma Transfer Arc (PTA) is ineffective. EMEX™is available in a range of thicknesses and is designed to help with weight reduction by applying thinner layers. Base Material EMEX™overlay can be applied direct to shaped items as well as to standard base material such as mild steel plate of varying thicknesses,
Multiclad wear plate is an extremely tough, wear resistant chromiumcarbide overlay on mild steel backing plate. Ideal for use in extremely abrasive, high impact and high temperature environments. Wear plate helps to extend component life, minimizes downtime and increase production. All our wear plate is manufactured in house on our purpose ...
Wear rates of Chromeweld have been shown to outlast most every material except ceramic. CHROMEWELD 600 plate is a mild steel backer plate clad with a series of Hypereutectic matrix overlay weld beads. The physical appearance of the plate will demonstrate numerous hairline cracks, which are a natural stress relief phenomenon.

apply as an overlay, compared with the traditional cobaltbase wear alloys. With ULTIMET alloy, cracking of the overlay is not a consideration, and multiple layers may be applied, with little or no preheat. Product Forms ULTIMET alloy is available in most common wrought product forms: plate, sheet, billet, bar, wire, and covered electrodes.
loss effect. Wear loss is the main way of failure of all metal surfaces such as wear plates, especially in the strong abrasive wear, wearresistant steel is gradually worn and eventually fails. The hardness of wearresistant steel is an important factor affecting its wear. Generally speaking, the hardness of wearresistant parts is more ...

The tungsten carbide overlays were prepared using the Eutectic + Castolin GAP 3000 AC/DC PTA welding machine. Four welding powders containing macrocrystalline angular WC of various sizes were applied to mild steel base plate using PTAW. The powders were prepared with large carbides (80/+100 mesh), medium carbides (
