"Corrosion and Coatings I: Introduction and Basics" will be offered on May 5 and "Corrosion and Coatings II: Testing and Performance of Corrosion Protective Coatings" is scheduled for May 19. Both sessions, to be presented by Dr. Gordon Bierwagen, North Dakota State University North Dakota State University, at Fargo; land-grant and state supported; coeducational; chartered and opened 1890 as North Dakota Agricultural College, achieved university status in 1960. , are scheduled from 2:00-3:30 (ET). These sessions may be taken individually or as a series. Corrosion and Coatings I: Introduction and Basics This session begins with a general examination of the corrosion of metal substrates and corrosion as an electrochemical electrochemical /elec·tro·chem·i·cal/ (-kem´i-k'l) pertaining to interaction or interconversion of chemical and electrical energies. e·lec·tro·chem·i·cal adj. process, a description of what must be present for corrosion to occur, and definitions of the basic types of corrosion. Special attention will be paid to the corrosion of steel and aluminum--the metals most commonly protected by organic coatings. Next, discussion will focus on the means by which metal substrates can be protected from corrosion including through coatings. Surface preparation of substrates for the application of coatings and its crucial importance to the subsequent coating performance will be covered. A brief summary will be given on the basics of formulating corrosion protective coatings. A survey of the most commonly used corrosion protective coatings including Zn-rich primers, general industrial maintenance primers, automotive ED primers, and primers for aircraft will be given. The lecture concludes with a brief discussion of the types of polymers used in corrosion protective coatings. II: Testing and Performance of Corrosion Protective Coatings The second session focuses on the performance and testing of corrosion protective coatings, with specific examples of results for widely used coatings of this type. Corrosion testing is best separated into two classes: qualitative (visual and experience-based) and quantitative. The primary qualitative test is visual examination of coated metal panels in exterior exposure at a site with an environment known to be especially harsh with respect to causing corrosion failures in coatings. Other exposure conditions include immersion immersion /im·mer·sion/ (i-mer´zhun) 1. the plunging of a body into a liquid. 2. the use of the microscope with the object and object glass both covered with a liquid. in electrolyte electrolyte (ĭlĕk`trəlīt'), electrical conductor in which current is carried by ions rather than by free electrons (as in a metal). solution (both unheated and heated), immersion in boiling DI water, continuous heated salt fog exposure, cyclic cyclic /cyc·lic/ (sik´lik) pertaining to or occurring in a cycle or cycles; applied to chemical compounds containing a ring of atoms in the nucleus. cy·clic or cy·cli·cal adj. 1. wet/dry salt fog exposure, and alternating QUV QUV Relative Magnetic Bearing (radiotelegraphy) and continuous salt fog exposures. Quantitative measurements are mainly electrochemical in nature and include potentiodynamic scans, monitoring of open circuit potential (free corrosion potential), electrochemical impedance impedance, in electricity, measure in ohms of the degree to which an electric circuit resists the flow of electric current when a voltage is impressed across its terminals. spectroscopy spectroscopy Branch of analysis devoted to identifying elements and compounds and elucidating atomic and molecular structure by measuring the radiant energy absorbed or emitted by a substance at characteristic wavelengths of the electromagnetic spectrum (including gamma ray, , and electrochemical noise methods. These methods may be performed in immersion or after exposure. A discussion of how these methods are used to evaluate coatings is presented, along with results from various types of corrosion protective coatings. The lecture concludes with a discussion of lifetime prediction for coatings from test results. Who Should Attend These sessions are intended for R & D personnel, technology managers, quality control/reliability engineers, and industrial coating An industrial coating is a paint or coating defined by its protective, rather than its aesthetic properties, although it can provide both. The most common use of industrial coatings is for corrosion control of steel or concrete. specialists involved in the coatings formulation, testing and manufacture. In addition, scientists that work with the manufacture and use of pigments will benefit greatly from these lectures as well as all those involved with architectural coatings, corrosion control coatings, military and marine coatings, or primers in general.
