The results showed that uniform corrosion,pitting,erosion corrosion and their interaction are the main causes of the failure of the PTA oxidation equipments in the environment containing acetic acid,Br~- and fluid steam and liquid.

The heating tubes in the 1st section mainly suffer from corrosion of dissolved oxygen while those in the 2nd section suffer from erosion corrosion of high-temperature steam.

Study on Erosion-Corrosion Behavior of Stainless Steel in Acidic Liquid-Solid Two-phase Flow;

In Field Electrochemical Detection and Erosion-corrosion Investigation of Metallic Materials in Marine Environment;

The influences of tungsten and carbon content on microstructure,hardness,impact toughness and erosion-corrosion resistance of these cast irons were investigated by metalloscope,image analyzer,X-ray diffraction,electron probe analyzer,mechanical properties test and low angle erosion-corrosion test in salt water sand slurry in this paper.

Using selfmade simulation test stand for copper tubes in condenser of turbines,simulated test of tube erosion for NiP and NiW plated coating and brass HSn 701A has been carried out.

The resistance to erosion and cavitation-abrasion of the two steels were evaluated by mass-loss method,and corrosion surface morphologies were observed by SEM.

With the self-made erosion test device,the erosion test of HSn70-1A brass and HA177-2A brass was carried out,and the right experiment data were matched into curves.
