Numerous materials are currently being developed and tested to assess their effectiveness in the corrosion and abrasion environment.
The materials were coated on the surface of 45 steel plates.
The mass loss of Zinc-aluminum coating are the highest and far more than those of the other three kinds of materials.
Microstructure of the frictional surfaces In order to explore the wear-reducing mechanism of the four kinds of materials, microstructure of the worn surfaces was observed by SEM.
With increase of concentration of sulfuric acid solution, corrosion potentials of these materials increase, which indicates that coatings in low concentration of sulfuric acid has higher corrosion tendency.

In plane lapping, workpiece material removal and lapping wheel wear has been influenced each other and should be evenly distributed.
Introduction Lapping is one of the few methods available for machining material, which are difficult to cut (e.g.

Experiments Materials and sample preparation.
The d001 peak of the pristine clay was shifted to lower value when mixed with the epoxy to form the nanocomposite materials.
Both materials i.e. neat epoxy and epoxy-clay-nanocomposite gained mass due to the environmental solution uptake, as shown in Figs.3 and 4 for water and acid respectively.
