Brett*, † Electrochemical Innovation Lab, University College London, London WC1E 7JE, United Kingdon ‡ Department of Chemistry, University College London, London WC1H 0AJ, United Kingdom ABSTRACT: Graphitic carbon nitrides are investigated for developing highly durable Pt electrocatalyst supports for polymer electrolyte fuel cells (PEFCs). Three different graphitic carbon nitride materials were synthesized with the aim to address the effect of crystallinity, porosity, and composition on the catalyst support properties: polymeric carbon nitride (gCNM), poly(triazine) imide carbon nitride (PTI/Li+Cl−), and boron-doped graphitic carbon nitride (B-gCNM). Following accelerated corrosion testing, all graphitic carbon nitride materials are found to be more electrochemically stable compared to conventional carbon black (Vulcan XC-72R) with B-gCNM support showing the best stability. For the supported catalysts, Pt/PTI-Li+Cl− catalyst exhibits better durability with only 19% electrochemical surface area (ECSA) loss versus 36% for Pt/ Vulcan after 2000 scans. Superior methanol oxidation activity is observed for all graphitic carbon nitride supported Pt catalysts on the basis of the catalyst ECSA. 1. INTRODUCTION nanoparticles agglomerate into larger particles and/or detach Among the various types of fuel cells, polymer electrolyte fuel from the support material, consequently reducing the electro- chemical surface area (ECSA) and catalytic activity.5,6 cells (PEFCs) have attracted the most attention for trans- ff portation and portable applications. Advantages include the To solve this issue, much e ort has been directed toward the following: rapid start-up and shut down, low temperature development of alternative, chemically stable catalyst supports.

Wildner, Plansee Holding AG, Reutte (2001), Vol. 2 Novel Composite cBN-TiN Coating Deposition Method: Structure and Performance In Metal Cutting W.C. Russell, A.P. Malshe*, S.N. Yedave*, W.D. Brown* Valenite Inc., Troy, Michigan, USA *MRL-MEEG, University of Arkansas, Fayetteville. Arkansas, USA Summary: Cubic boron nitride coatings are under development for a variety of applications but stabilization of the pure cBN form and adhesion of films deposited by PVD and ion-based methods has been difficult. An alternative method for depositing a composite cBN-TiN film has been developed for wear related applications. The coating is deposited in a two-stage process utilizing ESC (electrostatic spray coating) and CVI (chemical vapor infiltration). Fully dense films of cBN particles evenly dispersed in a continuous TiN matrix have been developed. Testing in metal cutting has shown an increase in tool life (turning - 4340 steel) of three to seven times, depending on machining parameters, in comparison with CVD deposited TiN films. Keywords: Cubic boron nitride, cBN, titanium nitride, TiN, electrostatic spray coating, ESC, chemical vapor infiltration, CVI, composite coating 1. Introduction: Diamond is the hardest known material and likewise the hardest material used in the cutting tool industry. However, since carbon is soluble in iron, diamond does not hold up well in applications on ferrous materials where significant cutting temperatures are generated. Cubic boron nitride (cBN), known as the second hardest material, has good thermal stability and chemical inertness with respect to ferrous materials.
