Paper Abstract

Increasing attention been given lately to focused on the laser—induced transfer technique in which metal coating are formed on the localized surface areas [1,2,3J. Resent interest in this technique has been spurred by its perspective to become an alternative for the well—known methods of local coating formation which are based on metal deposition out of photolitic, pyrolitic and photothermal liquid or gas metalliferous compounds [4]. Physical process which is the basic of the forward transference technology is the so called "The Laser—Induced Forward Transfer (LIFT) technique, and it includes 2 steps which are independent at the first sight: — thermal damaging of the donor film, deposited on the transparent insulative substrate, which was induced by radiation of the pulsed laser directed from the substrate; — depositing the products of destruction on the acceptor substrate. The difference from the well—known laser—beam evaporation methodic that the substrate (acceptor) is disposed in parallel to the target(donor) at a distance of one order, where the diameter of the laser—beam radiation zone is usually 10-100 mkm. According to on the analysis of the publications, in which the problem was studied, it may be concluded that the transfer process model has not been well formalized yet. Also, the process itself is poorly reproducible, and it is difficult to optimize it practically. In this paper we propose a mathematical model of the process. Accordingly. all the steps of the process are presented as a closed system, which varies with the time.It is therefore possible to provide single—valued interpretation of the result of simulation and experiment.
