Typical Applications for Plasma Ion Nitriding, Molds for casting of nonferrous metals and alloys, Surface Finishes produced by various Manufacturing Processes. How Google uses data when you visit this site. With a wide range of process control and optimization possibilities, plasma nitriding makes it possible to achieve stringent requirements not capable by gas or salt bath nitriding.
This is followed by Plasma Nitriding up to 60-80 microns. We envisage by two step process i.e first Hard Chrome plating up to 100 microns with Hardness 1000 Hv. This process permits the close control of the nitrided microstructure, allowing nitriding with or without compound layer (white layer) formation. are controlled. Will my part have any growth and/or shrinkage from UltraGlow® Ion Nitriding? It produces a compact, dense and more "ductile" compound layers than other nitriding processes, Improved surface finish and much cleaner surfaces as compared to salt bath and gas nitriding. It is the most technically superior of all nitriding processes and has many advantages compared to traditional salt bath and gas nitriding. }); High voltage is then applied between the work pieces and the furnace wall. Great surface finish: no additional mechanical treatments are necessary. If you need a product/service, please check these Directories: JobshopsCapital Equip. Matthew, It is very difficult to answer you question precisely with regard to adhesion of deposits on Nitrided mild steel. (View video of our longest part ever here.). Due to increased compressive stregnth at the part surface, fatigue strength is improved five to ten times its typical "non-treated" life, dependent on the material and part design. Plasma nitriding normally occurs at temperatures of 450 to 600 °C in a vacuum with the aid of plasma generated by a glow discharge on the workpiece surface. new LazyLoad({ The Plasma Ion process is done in a vacuum vessel at low temperatures (750°-1040°F or 400°-560°C) where high-voltage electrical charge forms plasma, causing nitrogen ions to accelerate and impinge on the metal. Reproducible results and better control compared to gas nitriding: the process of plasma nitriding is fully automated and computer controlled. The process is eco-friendly, saves energy and causes little or no distortion. Reusable masking (versus coatings or other surface treatments), Adds performance, fatigue strength and endurance, Increases material flow in molds and dies.
Sincerely, Matt. If you have pulsed plasma the job will be easier. Richard, Does Nitriding a mild steel affect the adhesion of a Nickel/Phosphorous deposit?
You can use either a copper based "stop off" paint to mask (from specified supplier) or use solid masking with mild steel rings, although this will be difficult practically as you are best treating the tubes vertically. Our MidPort Blvd. These nitrides eventually channel their way through the material’s grain boundaries, diffusing into the part leaving behind a hard, non-distorted, smooth surface. When the nitrogen ions bombard the part they heat up the metal, clean the surface, and absorb nitrogen into the surface.
View video of our longest part ever here. Easy masking: surfaces requiring selective treatment are easily masked with reusable mechanical masking devices that are 100% effective. We are looking for Plasma Nitriding of a Austenitic SS Hollow Bar of 1 M Long. We are looking for Plasma Nitriding of a Austenitic SS Hollow Bar of 1 M Long. A plasma nitrided part is usually ready for use directly after treatment requiring no machining, polishing or any other post-nitriding finishing operations. As the process gases begin to activate (ionize), a corona discharge (violet glow) takes place in the treatment chamber.
Further information is required on the distortion/ deformation during nitriding as it involves high temperature. This ion bombardment can create intense heat in the work piece and must be controlled. You will have to stand the tube on spacers to allow the plasma to "escape" t the bottom or you will overheat and get gross distortion.
