Academician: Watch out the “invisible killer”

"Corrosion is a destruction that undergoes quietly, but losses caused by which is enormous. Corrosion is an irreversible process of oxidation of the metal." Chinese Academy of Engineering academician Mr. Hou Baorong has spent lifetime combating this invisible enemy and he has profound understanding of corrosion damages.

 

 
  
The United States released the 7th Corrosion Cost Report in 2001: the corrosion caused a direct economic loss of 3.1 percent of America GDP since 1998. If calculated by 3%, the corrosion loss in 2014 was about 2 trillion yuan, which is far higher than the sum of economic losses caused by natural disasters." Academician Hou Baorong said, marine environment is the most corrosive environment, and in recent decades, the incidents caused by marine corrosion are occurring constantly.

Mr. Hou said the living example of marine corrosion is even more shocking. "In the waves splash zone, where corrosion is most severe, the average domestic steel corrosion rate is about 0.5 millimeters per year." Mr. Hou said, "Currently, almost all ports, docks and other steel structure in harsh environments are facing serious corrosion threat. Corrosion status of steel structure is even more worrisome. We’re 20 years behind the developed countries." 

   
2014, the first corrosion cost investigation project chaired by Mr. Hou was funded by the Chinese Academy of Engineering. As a major consulting project, it was named as “China’s Corrosion Investigation and Control Strategy."  A national commission was established with more than 20 academicians included. With two-year period, they will conduct a national census of corrosion cost and the report will be submitted directly to the State Council.

 

 Hou Baorong and his team developed Petrolatum Tape and Covering System (PTC)  focusing on the  wave splash zone, as well as for Oxidation Tape and Covering System(OTC)  for nuts and bolts, cable bridges and other abnormal joints , which all have made important breakthrough and widely applied in many major projects.
