BECOME A MEMBER AT NASF.ORG Navy SEAL to Keynote NASF Management Conference NASF is pleased to announce Rob O'Neill as the keynote speaker for next year's management conference to be held Feb. 26, 2014, in Maui, Hawaii. O'Neill is one of the most highly-decorated combat veterans of our time. He was a team leader with the Naval Special Warfare Development Group. He has deployed more than a dozen times and held combat leadership roles in more than 400 combat missions in four diferent theaters of war. A highly-trained Navy SEAL, he led the military's Fact Sheet Available: White House Executive Order on Improving Chemical Facility Safety and Security most elite and was involved in our nation's most important campaigns. He was one of the quiet professionals performing the most dificult tasks in the most dificult circumstances, serving his remarkable career in the shadows and keeping America safe in the process. In his line of work, instant, critical decision-making is an absolute necessity for success, and he has proven experience in exceptionally high-risk and fuid environments. Having trained more than 800 special operations and tactical operators, O'Neill brings this unique expertise to the NASF Management Conference next February. In O'Neill's talk, he'll translate his elite SEAL team training into actionable insights on leadership, decision-making, operating in uncertain environments, and how to become the best of the best. Companies using or storing chemicals may have missed that President Obama signed an Executive Order to improve the safety and security of chemical facilities and reduce the risks of hazardous chemicals to workers and communities. Chemicals and the facilities that manufacture, store, distribute and use them are essential to economic growth. However, incidents such as the explosion at a fertilizer plant in West, Texas earlier this year are tragic reminders that the handling and storage of chemicals present serious risks that must be addressed. When the cause of the Texas explosion was still under investigation, the President issued an Executive Order that says companies can take common sense steps to improve safety and security and reduce the risks associated with hazardous chemicals. "Electrodeposition of Ni-Fe-Mo-W Alloys," is under the direction of Professor Elizabeth J. Podlaha-Murphy, who has been active in electrodeposition for more than 20 years and currently leads eforts in the understanding of reaction mechanisms and kinetictransport behavior governing electrodeposition. There are a number of industrial applications for electrodeposited molybdenum (Mo) and tungsten (W) alloys due to the versatility of properties that the alloys impart. For example, the corrosion resistance is largely improved over that of nickel (Ni) or cobalt (Co) alone, thus they have been identifed as potential replacements for chromium. The addition of iron to tungsten alloys has been shown to improve the adhesion of nickeltungsten (NiW) alloys to steel and copper with high hardness. The magnetic properties of Ni, iron (Fe) and NiFe can be tailored through the addition of Mo or W. Their enhanced hardness combined with improved wear resistance, primarily for the W-alloys, make them ideal for microelectromechanical structures (MEMS) and micro-tools. In these applications, the control of the composition and structure is paramount to obtain the desired property, and since the deposition of these alloys are not well understood, the plating conditions are largely determined empirically. The goal of the project is to develop an environmentallyfriendly, non-ammonia plating bath that can be used for both Mo and W alloys, and that minimizes or eliminates crack formation, and in doing so build a toolbox for the electroplating community. The project targets the development of practical plating conditions for Mo and W alloys. The results generated will build a toolbox where platers can pick and choose operating conditions for the desired composition of interest. While the fundamental aspects of some of this work have been funded by other federal grants, they do not cover the practical aspects of maximizing current eficiency and reducing cracks in the deposit. Since the applications of these alloys are vast, it is expected that there is considerable interest across felds in the electroplating community. The following report details the work accomplished in the frst quarter of 2013 (January-March). Diferent aspects of the alloy deposition project were considered in parallel, with experiments utilizing Hull cells, investigation of the efect of additives and pulse deposition, all from a more environmentally friendly, non-ammonia electrolyte. The work was divided into three sub-projects involving the nickel-molybdenum-tungsten and nickel-tungsten systems. The frst was a rotating Hull cell study at a variety of current densities and temperatures to determine the conditions required for deposition of the alloy. The second dealt with the efects of pulsed deposition on deposit composition. The third was a Hull cell study into the efect of thiourea on the deposition. The full paper can be accessed and printed from short. pfonline.com/NASF13Oct2. The complete report on the AprilJune 2013 quarter will be published in the NASF Report in the November issue of Products Finishing. PRODUCTS FINISHING — pfonline.com 15
