Secrets of C.A.S.E to be unveiled at Engineering Materials Live
Chemically Assisted Surface Enhancement, or CASE, is an isotropic superfinishing process which has been developed as a metal surface treatment to provide components with excellent bending and contact fatigue strength, together with resistance to high loading.
Secondary processing by further shot peening (or dual peening) at a lower intensity with modified shot size will have the effect of reducing surface roughness and increasing the compressive stress and cold working of the near surface.
Final processing is then carried out in a controlled and gentle manner using non-abrasive finishing stones together with oxalic acids: here, the most positive or peak surface areas are progressively removed, producing a mirror-like surface finish with an extremely low surface roughness.
Some of the most common applications for isotropic superfinishing by Metal Improvement Company include the manufacture of gears, transmission shafts, bearings, cams and cam followers, journals, seal faces etc. Key benefits of isotropic superfinishing include achieving the optimum surface roughness and stress characteristics, being able to produce mirror-like finishes, the reduction of contact/surface fatigue and the prevention of micro and macro pitting. CASE is just one of many surface finishing options available to discuss on the Metal Improvement Company stand at the forthcoming Engineering Materials Live event on March 12th.
Engineering Materials Live is the UK’s only dedicated one-day advanced materials exhibition, and offers visitors a unique opportunity to meet and talk with some of the most experienced technologists and application experts in the country.
