The result shows that compared with pseudo alloy coatings,low-carbon martensite coating presents superior mechanical,anti-wear and machining properties which can be applied to engine components remanufacturing like crankshaft etc.

Effects of heat treatments on structure and properties of Mg-A1 Pseudo Alloy Coatings were studied.

The main bridge of Fumin Bridge in Tianjin is a single tower and spatial cable plane self-anchored suspension bridge and the construction technology of arc sprayed zinc-aluminum pseudo-alloy coating is applied to the corrosion protection for the stiffening steel box girders of the bridge.

Based on the technology of Co-B and Co-P alloys nanocrystalline coatings, the ternary Co-Ni-B and Co-Ni-P nanocrystalline alloy coatings were obtained, and the deposit rate and microstructure of ternary nanocrystalline alloys were investigated.

Results showed that satisfactory alloyed layer could be also formed on steel castings without adding fusing agent into alloy coating.

The Ni-based alloy coating and Ni-clad WC ceramic coating were prepared and characterized by abrasive wear resistance test.

In virtue of electron energy spectrometer, X-ray diffractometer and scanning electron microscope, the effects of rare earth yttrium on chemical composition and structure of the vacuum fusion sintering NiCrBSi alloy coating were studied.
