Biomachining of Stainless Steel Using Bacteria
Search this Article
Bacteria having the ability to produce corrosion pits on metal surface were detected from a Microbiologically Influenced Corrosion (MIC) failure case analysis. To apply the corrosive ability of these bacteria to material processing is the aim in the present study. This is a new type of machining process utilizing biological principles. Hereinafter this process is expressed as biomachining. To investigate the possibility of biomachining, the following experiments were planned. In the 1st experiment, Bacillus sp., detected as the cause of the corrosion of stainless steel in an MIC failure case, was selected as the test strain for processing. Also, the optimal conditions for machining in the case of Bacillus sp. were examined. In the 2nd experiment, a prototype of bioreactor for processing was designed. An experiment for biomachining using this reactor was carried out.
