Surface Engineering provides a variety of wear resistant products designed to address wear problem of all types. In order to make the best product selection for an application, the wear mode or modes contributing to a components degradation must be assessed and understood. In most situations, there is a combination of wear modes that reduce the lifetime of a component. However, there is normally only one characteristic of wear causing the majority of the damage.
- Pitting, - Spalling, - Impact, - Brinelling
- Low Stress, - Hight Stress, - Gouging, - Polishing
- Fretting, - Adhesive, - Sizure, - Galing, - Oxidative
- Solid Impingement, - Fluid Impingement, - Cavitation, - Slurry
Many are available in different forms as described below. Surface Engineering Alloy Co.
can assist you in the best choice for application of the articular alloy or composite.
Cast, sintered or tube rods for hardsurfacing are available from .045” to ½” diameters for Oxyacetylene or TIG (Tungsten Inert Gas) welding. The manufacturing method depends mainly on the product, diameter and welding process required.
Most of the products listed in our literature are available in the form of welding electrodes. The available size range from 3/32” to ½ “ diameters. Some of the electrodes are manufactured by putting the alloy elements into the core of a steel tube and subsequently coating the tube. Other electrodes are manufactured using alloy rod and extruding coating containing additional alloying elements which will produce the final chemistry for welding.
Solid and Metal or Flux-Cored Wires are available from .035” to 1/8” diameter for MIG (Metal Inert Gas), TIG, Submerged Arc (SMAW), and Open-Arc welding (OAW). Most of the alloys listed in our literature are available in wire form. This is a very efficient method for hardfacing and it is often a very good idea to use the available wire form for the alloy required.
Powdered metal alloys, ceramics and composites are available in virtually all size ranges for the array of application methods utilized in industries. Surface Engineering Alloy Co. supplies both gas and water atomized powders for Spray-Fuse and PTA applications as well as Clad, Spray Dried, Crushed and Sintered powders for the various Thermal Spray methods. Mesh sizes are tailored to meet application equipment specifications, providing for consistent weldability, spray characteristics and deposit quality.
Most of the hardfacing alloys can be used to produce castings of all sizes. Castings are manufactured via Investment, Static, Sand, Shell, Ceramic, Centrifugal and Lost Foam processes. Castings offer value when the wear resistant component is small or difficult to hardface, when the tolerance for wear is greater than the thickness capability of hardsurfacing or the labor and processing costs for manufacturing the hardfaced component exceed those of casting.
The only common hardfacing alloys available in the form of wrought plate or bar stock is the Cobalt base alloy #6 and Ultimet®. However, virtually all corrosion resistant and aerospace alloys are available in various diameters of bar stock or plate thicknesses.
Surface Engineering Alloy Co. provides Dental Ingots of various alloys, sizes and shapes. Rectangle, square and round hipped rod to the saw tipping industries, ceramic and tungsten carbide tiles of various sizes and shapes, cast wear pads containing ungsten carbide in various alloy matrix, Certified Master Alloy and remelts, including scrap alloys to the casting industry, and any other specialty product that may be required to meet the demands of the industry.
