Abstract
The variation in surface microrelief of the aluminum-lithium ahoy Al-2 % Li-2.5% Cu and pure aluminum as a result of irradiation by powerful pulsed hydrogen-plasma fluxes at heat-flux densities of 10(5)-5.10(6) W.cm(-2) and pulse length 20 mu sec is investigated on a Desna unit. T he minimum heat-flux density from the high-temperature plasma required to initiate surface melting of aluminum materials is determined. The temperature and corresponding vaporization rate from the sample surfac e are estimated for several characteristic heat-flux densities.
