Other applications
The wear and the fatigue of materials, common concerns in all sectors, cause huge economic and environmental costs. For this reason, the list of applications for CRYOBEST® multi-stage cryogenic treatment is very varied and practically endless.
As an example we have resistance welding electrodes, which are manufactured with copper alloys with a good balance between mechanical resistance and conductivity. The CRYOBEST® process improves their performance, sometimes spectacularly. It also gives good results on copper welding contact tubes and on tungsten electrodes.
Another quite popular application, particularly in the US, is the treatment of brake discs. These components are usually manufactured using GG25 grey cast iron, a material which responds well to the process. The treated discs last much longer; they do not bend or crack and are more resistant to fading. For this reason, they are used in service vehicles (taxis, ambulances, police cars, etc.) as it improves their performance reducing costs at the same time.
The world of motor racing is another sector with various different applications of the process. Apart from the brake discs already mentioned, all kinds of engine and transmission components (blocks, cylinder heads, crankshafts, rods, pistons, springs, pinions, gear boxes, clutches, etc.) are treated. The treated components last longer and are more reliable, notably reducing the costs and the number of incidents during the races (“to finish first you must first finish”).
Applications which aim to increase fatigue life are becoming more common due to the good results provided by the process. There are more and more studies and experiences, on different materials, which confirm this technology’s capacity to significantly increase this property. Steel for springs, for bearings, case carburized, stainless steel, aluminium alloys, etc. are among these materials and there are now quite a few successful examples such as the clamps for multispindle lathes . This type of application is likely to increase rapidly in the future in line with the increase in research in this field.
Another sector of application that has become popular is that of high-end audio components, where the application of the treatment on various different components (e.g. the cables) appears to improve the sound quality. In the US it is also common in the treatment of fire arm barrels (it contributes dimensional stability) and sports material like, for example, golf clubs.
