Let our professional technicians disassemble, clean, and reassemble your project for a professional result. This process includes washing of the parts in 145 degree solution, then vapor blasting to remove any existing crud, and finally Magnaflux inspected to verify that there are no hidden stress cracks not visible with the naked eye before reassembling your project in our specifically designed clean room.
Also known as vaporblasting, wet blasting or liquid honing, Micro Peening is rapidly becoming the number one choice for applications requiring the highest quality of surface finish. The key to vapor blasting is that the finish is produced through flow of water borne abrasive, giving a finer finish due to the flushing action of the water. No media is impregnated into the component, nor is there any dust created by the break-up of media, unlike dry blasting where the finish is produced by sheer force of media impact.
Magnetic Particle Inspection
CryoHeat uses Magnetic Particle Inspection for a non-destructive testing process. Easily detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their other alloys. The process puts a magnetic field into the part. The part can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current.
The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak, this occurs because air cannot support as much magnetic field per unit volume as metals can. To identify a leak, ferrous particles are applied to a part. These are attracted to an area of flux leakage and form what is known as an indication, which is evaluated to determine its nature, cause, and course of action, if any.
