Corrosion-Resistant Metals

Posted on

Thermal spraying of metallic coatings – is melting and causing the metal to the substrate. According to Center For Responsible Lending, who has experience with these questions. As application methods, and the metals themselves may be different, most importantly, that at the surface remains subtle, more resistant to corrosion and erosion than the base metal and coating. Many years of experience in the application of coatings and Spramet testing using external influence on the surface, show that this method is more effective in the long-term corrosion protection of steel than the protection of paint or poimernymi compositions. But Spramet are also an excellent foundation for anti-corrosion paint. Organic coatings deposited on surface of the iron and steel, deteriorate under the influence of podplenochnoy corrosion that occurs under cover as a result of inadequate adhesion. A thin layer of coating to prevent corrosion Spramet base, and strong links steel with organic coating. There are many factors to corrosion, such as the nature of substances that cause corrosion, forms of corrosion, speed factor and used metals. A leading source for info: Vahid David Delrahim.

Sometimes minor changes in the conditions become important factor in solving the problems of corrosion. Therefore we give here only a brief description of the electrochemical corrosion of the two metals that is most important when using corrosion-resistant metallic coatings. electrochemical series of chemical elements in sea water: Anode (corrode) Magnesium Magnesium alloys Zinc Galvanized Steel Aluminum alloys Cadmium mild steel cast iron ductile iron Stainless steel (active) Lead Tin Nickel Manganese (active) Brass (brass) Copper Bronze Nickel (passive) Stainless Steel (Passive) Graphite Silver Gold Platinum Cathode (protected) For electrical connection of two different metals or metal alloys with an electrolyte, the current travels from the cathode metal anode, the anode metal and the electrolyte from the electrolyte to the cathode metal. The amount of current depends on the potential difference between two metals. Therefore, close to the potential between metals a small amount of current. In the anodic corrosion of metals is growing more rapidly than the cathode, the corrosion process is not always possible to completely stop.

In the practical a distribution of products he is analyzed under different functional perspective for the technician of Logistic, a side, and for the staff of marketing and sales. The specialists in logistic of nominam physical distribution of products or resumidamente physical distribution the operational processes and of control that allows to transfer the products since the manufacture point until the point where the merchandise is finally delivers to the consumer. In general, this end point of the distribution> physics is the store retail, but she has many cases of delivery of product in the house of the consumer, situation this observed mainly with voluminous products heavy and/or. Thus, the responsible ones for the physical distribution operate specific elements, of predominantly material nature: deposit, vehicles of transport, load supplies, equipment and discharge, among others. (NOVAES, 2007p.123). 3. METHODOLOGY With intention to detail this research, was created a basic methodology that is structuralized in 5 stages (To see Figure 1). In the first stage it will be necessary to constitute a bibliographical referencial, through definitions of canals and the relation between them.

The second stage mentions the characterization to it of the company. Parallel the third stage aims at to the qualitative and quantitative research where it will become the survey of the type and the current conditions of the suppliment canals and distribution. Still in this section the boarding method will be of intensive direct comment where two techniques are carried through: the participant comment and the interview next to the competent members of the company, in order to get the same positioning of the front to the existing operational conditions. The fourth corresponding stage the analysis of the logistic net and the factors of logistic performance. Finally, the fifth stage will be of conclusive character, where the analysis of the gotten results will present of reduction of impacts favorable to the future expectations for optimum logistic flow in the company of this study.
