Forming a conductive film comprising depositing a non-conductive film on a surface of a substrate, wherein the film contains a plurality of copper nanoparticles and exposing at least a portion of the film to light to make the exposed portion conductive. Exposing of the film to light photosinters or fuses the copper nanoparticles.

A process for making a composite product comprises the steps of: A. Circumferentially plating a carbon fiber core with an alloy film including a film of high entropy alloy and liquid metal alloy or a film of metallic glass to form a film-clad carbon fiber thread; B. Weaving a plurality of said film-clad carbon fiber threads to form an interlaced film-clad carbon fiber sheet; and C. Vibrationally thermally pressing a plurality of said interlaced film-clad carbon fiber sheets as superimposed with one another to form a composite product.

In some embodiments, the effect of uniformly dispersing carbon nanotubes in the material is achieved by including Ag in the carbon nanotubes to suppress the aggregation of carbon nanotubes when the electrical contacts are prepared.

The present disclosure relates to a wear part having high wear resistance and strength and a method of making the same. The wear part is composed of a compound body of cemented carbide particles cast with a low-carbon steel alloy. The low-carbon steel alloy has a carbon content corresponding to a carbon equivalent Ceq=wt % C+0.3(wt % Si+wt % P) of about 0.1 to about 1.5 weight %. The wear part could include a body with a plurality of inserts of cemented carbide particles cast into a low-carbon steel alloy disposed in the body. Each of the plurality of cemented carbide inserts are coated with at least one layer of oxidation protection/chemical resistant material. The plurality of inserts are directly fixed onto a mold corresponding to the shape of the wear part. The cemented carbide inserts are then encapsulated with the molten low-carbon steel alloy to cast the cemented carbide inserts with the low-carbon steel alloy.
