INFLUENCE OF THERMAL ACTION ON THE EFFECT OF INCREASING THE CARRYING CAPACITY OF ROTATING DISKS WITH THIN HIGH-MODULUS COATINGS

Based on the general concepts of the linear theory of unbound thermoelasticity, the problems on calculating the temperature fi elds and mechanical behavior of rotating disks with strengthening coatings have been formulated. A single numerical method has been developed for integrating the posed thermal conductivity and thermoelasticity problems, and concrete calculations of the carrying capacity of layered disks were performed. It has been established that the presence of defi nite temperature fi elds in a layered disk may hinder its strengthening of the disk surface covered with a thin high-modulus coating of thickness 0.1–0.6 mm that sharply strengthens the disk at the temperature of its natural state
