Dependence of intrusion depth (a) s from h (1, 3-T = 373.15 K; 2, 4-T, = 293.15 K)Theoretically the process of heat transfer when intruding steel particles into ice lining at small rate due to thermal energy has been investigated. Obtained digital results allow to make a conclusion concerning realization possibility of such mechanism in sputtering powder covering and are the basis for further development of the stated model.The list of designations Figures: 1, 2, 3 correspond to the particle, lining and melt area correspondingly; Ttemperature, K; T, -particle temperature, K; r, z -cylindrical coordinates ; hlongitudinal particle dimension on transverse particle dimension on coordinate r, mm; r2 transverse lining dimension on coordinate r, mm; r3 -typical dimension of melt area on coordinate r, mm; Llongitudinal lining dimension on coordinate z, mm; d --thickness of melt area, mm; Re -Reynolds number.
