Porous nanocrystalline Ti(C_xN_(1-x))thick films firmly bond to the substrate were obtained on commercial pure titanium by plasma electrolytic carbonitriding(PECN).

Pilot test for treating wastewater from nitrile rubber unit by ferric-carbon micro-electrolysis

The effect of ferric-carbon micro-electrolysis-effective synthesized microbiology is studied in this paper.

Tebuconazole waste water with high concentrations of COD,complex composition,and weak biodegradability,first of all, recycling waste water in the N-methyl pyrrolidone,and then using iron carbon micro-electrolysis and ozone oxidation for waste water treatment.

First of all,the chlorine oxidation method was used to recycling bromine from the waste water,and then iron carbon micro-electrolysis method was used to the treatment of waste water.

The wastewater from explosive production was pretreated by iron-carbon micro-electrolysis process,and the effluent was treated by alkaline coagulation/aeration.

The iron-carbon micro-electrolysis process was used to treat furfural wastewater.

The wear resistant composite materials on the base of aluminium oxide with ZrO 2 were prepared using the technology of hot press and microarc oxydation.

According to the traditional nucleation-growth kinetics theory,with the estimation of relative parameters such as the transformation free energy and the interfacial energy,a relative quantitative theoretical calculation method for the PTT(precipitation amounttemperature-time) curve of microalloy carbonitride precipitated in ferrite is proposed.

The theoretical formula for the composition of the binary microalloy carbonitride and the solubility of related elements in austcnite were deduced according to the thermodynamic theory,thereby the effects of steel com- position on the carbonitride composition have been discussed and some in- structive conclusions have been obtained.
