The role of sandwich Cu layer in and effect of self-bias on structural and nanomechanical properties of Cu/DLC bilayer films have been explored. Cu/DLC bilayer filmswere grown, under varied self-bias from−125 to−225V, using hybrid system involving radiofrequency(RF-) plasma-enhanced chemical vapor deposition and RF-sputtering units. Surface topography and mean roughness was studied by atomic fo...

The intumescent retardant coating was fabricated by a combination of epoxy binder and flame-retardant ingredients for the steel plate. This paper investigates influence nanoclay content on improving fire properties fire-retardant coatings. performances coatings were determined test at 950oC one hour. degradation characterized Thermal gravimetric analysis (TGA). morphology, composition char stud...

The purpose of this work was to use different surfactants deposit crystalline calcium carbonate films on the surface sandstone through a simple double displacement reaction. This done test protective effects coatings based water absorption, moisture permeability and weather resistance. Experimental results showed that air stone treated with vaterite reduced, but did not affect vapor’s access in...
