Research of the temperature fields influence on the stress state of internal cylindrical surfaces modified by magnetron sputtering

[摘要] For material selection of protective metal coating, deposited on the products' surface with cylindrical symmetry by magnetron sputtering and exposed to intense heat loads during pulsed operation mode, it was executed numerical simulations of the temperature fields and the stress state caused by pressure and uneven temperature distribution. It was determined a coatings' material satisfying the minimum of internal stresses, which is one of the main criteria of their service life. Based on the calculation results titanium provides the maximum reduction in the internal stress while the usage of molybdenum as a coatings' material leads to the greatest decrease of pulsed temperature impact to the binary "steel-coating" systems with cylindrical symmetry.
