Hardening thermoplastic (TPU) large parts

This article describes applications of the method of thermoplastic hardening (TPU), as alternative methods of surface plastic deformation (PPD). Given the shortcomings of existing and introduced into production plants for thermoplast-IC hardening using heat-natural gas, which is used for domestic and industrial needs. Tasked with developing a radically new installation with elements of more automation and a more or less stable process of hardening through the use of electric heating. The developed device with a TPU case with electrical heating for local hardening of large-sized parts such as turbine disks of gas turbine engines (GTES) and other parts such as crowns large gear wheels. Described in detail the components of the installation and the whole process cycle of hardening. Advantages of the installation for thermoplastic hardening are compared with existing methods and realized installations in the production
