Dear friend Dheeraj Jaiswal

I remember answering similar a few days back. I will post link to that question when I find it.

The formation of a one-sided silver layer on an Ag-50wt.%W composite can be challenging due to the high melting point and refractory nature of tungsten metal. One possible solution is to use a brazing process that involves melting a silver alloy and allowing it to flow and bond with the surface of the composite material. The brazing process can be performed at a temperature below the melting point of tungsten to avoid its melting and subsequent diffusion into the silver layer.

Another approach is to use physical vapor deposition (PVD) techniques such as sputtering or evaporation to deposit a thin layer of silver on the surface of the composite material. PVD techniques can produce a uniform and adherent layer of silver with a thickness that can be controlled by adjusting the deposition parameters.

It is also important to ensure that the surface of the composite material is properly prepared before applying the silver layer. The surface should be cleaned and polished to remove any impurities or oxides that can interfere with the bonding or adhesion of the silver layer.
