The concentration of alloying elements and the thickness of the alloyed layer can be gradually increased by increasing the number of irradiation cycles.
Second, elemental arsenic does not combust with copper in alloying as in the case of arsenic sulfide.
In this case, the thickness of the alloyed layer is about an order of magnitude greater than that attainable on nanosecond laser alloying.
If, because of thermodynamic limitations, the film component content is comparatively low, the mode of nonequilibrium liquidphase alloying is realized.
I do not feel entirely satisfied, however, about the question of alloying metals.
I should have thought, therefore, that it would have been safer to have included these alloying metals among the other raw materials.
The experiments have been extravagant because time and again the whole of the alloying has been changed and new experiments tried.
The import of many of these alloying elements is the responsibility of private enterprise.
