Pits have been found to be a common source of crack initiation and the experimental procedure would prove useful in research in crack initiation. Pits generated using this technique were approximately hemispherical. It was seen that individual pits increased in radius at a linear rate of 0.33 mm h(-1) and depth at a linear rate of 0.39 mm h(-1). In the early stage of the process, single <span style=\"color:red\">pit</span> nucleation was the dominant process, and the area covered by pits increased to 1.7% in the first 40 h, and 75% of the pits were individual pits. In contrast, <span style=\"color:red\">pit</span> coalescence became significant in the later stages, and by 120 h the area coverage was up to 13.5% and only 50% of the pits were individual pits. The linked pits contained an increasing number of individual pits as time progressed containing up to five pits after 120 h and the linked pits tended to become more circular with time. The growth behaviour of linked pits was significantly different from individual pits. This study establishes some of the details of how pits nucleate, grow and link together. The published literature showed that the growth exponent of pits varied with the severity of the corrosion environment and the growth law determined here was at the high end of the published growth exponents.","authors":[],"categoryName":"|","doi":"","fpage":"32","id":"6846d337-3405-4d80-886b-32ed6dd3b011","issue":"1","journal":{"abbrevTitle":"CESAT","id":"ec8b0e7e-fc21-451a-9fbf-0d3334741d89","issnPpub":"1478-422X","publisherId":"CESAT","title":"Corrosion Engineering Science and Technology"},"keywords":[{"id":"5d51bd8a-7971-4c12-b3dc-228f357c68c1","keyword":"Pitting corrosion;X-52 steel;Individual pits;Linked pits;<span style=\"color:red\">Pit</span>;nucleation;<span style=\"color:red\">Pit</span> growth;Passivation/acid immersion technique;pitting corrosion;statistical characterization;stainless-steel;prediction;initiation;kinetics;depth","originalKeyword":"Pitting corrosion;X-52 steel;Individual pits;Linked pits;Pit;nucleation;Pit growth;Passivation/acid immersion technique;pitting corrosion;statistical characterization;stainless-steel;prediction;initiation;kinetics;depth"}],"language":"en","publisherId":"1478-422X_2009_1_1","title":"Passivation/immersion method to grow pits in pipeline steel and a study of <span style=\"color:red\">pit</span> nucleation and growth resulting from the method","volume":"44","year":"2009"},{"abstractinfo":"The thin, long length and high smoothness silica photonic nanowires and taper optical fiber were fabricated using a simple and low cost chemical etching method.
