USING INDUCTION HARDENING TO STRENGTHEN CAR PARTS

Abstract

The war waged by the Russian state against independent Ukraine posed new difficult tasks for society in the production and repair of damaged military equipment. In the conditions of a shortage of military equipment, carrying out repairs becomes a task that must be performed quickly and efficiently in order to replenish the armed forces of the state. In such difficult conditions, methods of high-speed processing should be used, including methods of surface strengthening of machine parts. The work is devoted to the improvement of technological processes of restoration and strengthening of parts of automobile and military equipment at repair factories under conditions of martial law. The efficiency of auto repair production is determined by the number of parts that are restored and continue to perform their functions with even better indicators than before restoration.Most parts have a residual resource and can be reused as a result of carrying out a relatively small amount of work on their restoration. The main methods of surface strengthening of machine parts are chemical and thermal treatment (cementation, nitriding, nitrocementation), surface plastic deformation, application of electrolytic coatings and surface hardening - laser and induction using high frequency current. The processes of chemical and thermal treatment are long-term and are not relevant in repair production in wartime. Modern mobile repair workshops prefer equipment and tools that are not metal-intensive and are able to perform technological processes in a short period of time. The most expedient at present is the introduction of technological processes using installations that produce high-frequency current and processes based on it.In the work, the authors conducted research and developed an inductor for hardening the rocker arm made of steel 45. The choice of the type of inductor and its calculation are based on the relevant conditions described in the work.In the work, the authors conducted research and developed an inductor for hardening the rocker arm made of steel 45.
