  • what is grit blasting
    oxide. Silicon carbide. Plastic. Walnut shell. Corn cob. Baking soda. Ceramic grit. Copper slag. Media selection is a crucial decision in the engineering of abrasive blasting processes. The different media types have different hardness, shape, and density, and each is available in a wide range
  • Refractory Hard Metals
    Refractory hard metals (RHMs) are a ceramiclike class of materials made from metal-carbide particles bonded together by a metal matrix. Often classified as ceramics and sometimes called cemented or sintered carbides, these metals were developed for extreme hardness and wear resistance. The RHMs
  • New Roles For Ceramic Parts
    , produces the parts with a proprietary injection-molding technique. Wafer carriers and other components used in semiconductor fabrication are traditionally made from quartz, but these are silicon carbide. A proprietary process from Poco Graphite, Decatur, Tex., converts the machined graphite structure
  • Small Hole Shot Peening Applications
    are 100% carbide, with deflector tips and exit geometries optimized for minimum energy loss. Table 2 summarizes the hole peening methods discussed and lists some criteria to consider when deciding which method to use. Keep in mind that it is almost always faster to peen holes using standard nozzles
  • Microabrasion: Controlling the Process
    oxide, glass beads, crushed glass, sodium bicarbonate and silicon carbide. We will recommend the best powder to suit your needs. Powder vs Cutting Speed. Nozzle Distance to Surface. Aside from the powder flow rate, the distance you hold the nozzle away from your work surface will also play a large
  • what is waterjet cleaning
    coatings and debris from substrates. The water jet stripping process removes these coatings with one of two different mechanisms: erosion or delamination. Erosion is used on the majority of hard coatings such as metal and carbide thermal spray coatings. A special nozzle is used to break up the water
  • How to use a Variable Speed Control to Optimize a Precision Grinding Application
    it acts. The higher the surface feet per minute the higher the friction. The higher the fric-tion the higher the heat. Now couple this with the kind of grinding wheels you use: Aluminum oxide, silicon carbide, diamond, CBN BORAZON® , etc., and the changes in speed are necessary. Grit size, hardness
