5 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke July 2009: Miba AG took a minority share (24.9%) of TCL full ownership is expected by the end of 2010. until then TCL remains a SME! The Miba Group is a leading international company, of ~2600 employees, headquartered in Austria. Miba is a leading strategic partner of the international engine and automotive industry. Mibas product portfolio includes sintered components, engine bearings, friction and coated materials. TCL & HTC (Mibas Coatings Competence Centre, with ~40 employees) will collaborate closely.

6 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke Routine Production Coatings: Hard coatings, e.g. for cutting tools, etc. –e.g. single nitrides TiN, CrN… & alloy nitrides TiAlN, CrAlN, CrTiAlN…, oxides, multilayers, etc. Self lubricating, low friction coatings for wear resistance –e.g. carbon based: TCL Graphit-iC& Dymon-iC; and MoS 2 based: TCL MoST Plus, coatings for corrosion resistance, electrical conductivity, optical properties, etc. Coatings typically 1-3µm thick, but… –nm to mm thickness possible for special applications

7 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke Coatings: a continually expanding range….

8 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke ….for many different applications…. Cutting Tools Gears, Bearings and other Wear Components Body Jewellery….!

9 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke ….including Coating of Powders & Grits! Barrel Coater (Load Locked) Coating sources project into barrel Powder exposed to coating flux

10 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke Unbalanced field. Field lines closed with another magnetron. Plasma confined around substrates. Electrons loss to chamber walls minimised. Increased ionisation. Dense, adherent coatings Typical energies 20-30eV, ideal for high quality film growth. Closed Field Magnetron Sputtering

11 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke FC&H 2 Example - coatings for bipolar plates: –TCLs magnetron sputtering technology is industrially qualified ideal for the deposition of thin, dense, well adhered, high quality coatings on a wide range of substrates (including metals and vacuum-stable polymers). –Product-specific results of TCLs previous work in this field are obviously confidential to the customers concerned! [V Fox: presented at - Manufacturing of Bipolar Plates event, Swerea IVF, Stockholm, 29th January 2008]

12 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke Metallic thin film coatings for bipolar plates: –dense, homogeneous coatings of metals are deposited at high rates –multiple elemental targets (typically 4 or 6) alloys and/or graded compositions easily created –compounds (nitrides, oxides, etc.) can be synthesised by reactive deposition reactive gas (e.g. N 2 ) introduced during the deposition process compound (e.g metal + nitrogen = MeN) formed in situ automatic feed back control (reactive gas flow slaved to metal content of the plasma)

13 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke Transition metal nitrides (e.g. TiN, CrN etc.) –hard, dense and relatively inert –routine coating sources up to 1m (>2m demonstrated!) –metallic levels of electrical conductivity –excellent adhesion (Rockwell and scratch adhesion results on M42 tool steel substrate shown below)

14 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke New high rate magnetron deposition of TiN: –2 magnetrons (12.5kW each) –50 mins deposition: total thickness 3.36 μm –deposition rate 4 μm/hr 4x higher than from conventional magnetrons –hardness: 33 GPa –scratch adhesion – L c >60N (i.e. very good) So, achieved 4x increase in rate with no obvious deterioration in coating quality

15 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke Graphit-iC coatings –originally developed for demanding, high load bearing, tribological applications contains ~5 at. % chromium hardness H = 10 to 40 GPa (selectable); Youngs modulus E* ~ 155 GPa low coefficient of friction (<0.1) very low specific wear rate (~ 10 -17 m 3 N -1 m -1 ) electrically conducting (like graphite) – high sp 2 content –conventional process, ~2µm takes several hrs

16 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke Graphit-iC Coating Process 3-steps: –in-situ ion cleaning –deposition of thin metallic Cr interlayer –deposition of C-Cr layer

18 Teer Coatings Ltd Hydrogen Energy Universities of Birmingham & Warwick, Hydrogen Energy, 22 nd January, 2010 © Teer Coatings, 2010 Kevin Cooke Graphit-iC coatings for bipolar plates: –power input can be increased by up to 3x cf TCLs conventional Graphit-iC coating process –deposition rates improved by 2 to 2.7x, say –here, 2-axis rotation improves coating uniformity. In- line systems with magnetrons sputtering simultaneously onto both sides of the plates could be used in a production process. –pure carbon or Graphit-iC coatings can be deposited at thickness ranging from <100nm to a few microns –coatings can be (have been) deposited with or without Cr adhesion layers –rates as high as ~5 µm/hour are already achievable for a stationary substrate (equivalent to 85nm per min)
