New Courses for 2018
These four new courses address the specific challenges, requirements, and applications associated with the products and technologies featured in our TechCon Symposia: Multi-Functional Thin Films – The Tailoring of Interfaces.
The complete schedule of all course offerings will be available in November 2017.
Thin to Thick Films: Growth and Microstructure Evolution
Dr. Joe Greene, University of Illinois
This tutorial is intended for scientists, engineers, technicians, and others involved with the vapor deposition of thin films by sputtering, evaporation, MBE, CVD, thermal spray, etc., and who need to obtain a better understanding of the effects of operating parameters on the properties of metal, semiconductor, and dielectric films and alloys. The tutorial is concentrated on the development of a detailed atomic-scale understanding of the primary experimental variables and surface reaction paths controlling nucleation/growth kinetics and microstructural evolution during vapor-phase deposition of thin films. The goal is to develop an appreciation of the advantages and disadvantages of competing growth techniques and to learn how to design better and more efficient film growth processes to achieve required properties. Thin and thick films are pervasive in many advanced fields of modern technology including microelectronics, optics, magnetics, hard and corrosion-resistant coatings, micromechanics, thermal barriers, etc. Progress in each of these areas depends upon the ability to selectively and controllably deposit films (thickness ranging from tens of Angstroms to micrometers to hundreds of micrometers) with specified physical properties. This, in turn, requires control—often at the atomic level—of film microstructure and microchemistry.
Sputter Deposition for Aerospace Applications
Dr. David A. Glocker, Isoflux Inc. (retired))
This course covers topics of practical importance to those using sputtering to deposit coatings for aerospace applications. It is intended for engineers, scientists and technicians who would like an understanding of the factors that influence product throughput, coating quality, and process robustness and reliability. It begins with a basic description of sputtering and sputtering plasmas and then illustrates the use of various techniques through specific applications. These include coatings for reducing friction and wear, optical coatings for filters and displays, coatings for sensors, and others. The relationships between the sputtering conditions and important film properties, such as microstructure, composition, stress, adhesion and the resulting mechanical, electrical, and optical characteristics are discussed. The emphasis is on process and hardware considerations rather than the detailed material properties of the coatings.
Characterization of Thick Films, Thin Films, and Surfaces,
Dr. Tom Christensen, University of Colorado/Colorado Springs
This course is intended for people with a basic background in materials science who need to understand the broad range of techniques available to characterize thick films, thin films, and surfaces. The course is appropriate for technicians, engineers, and managers who perform or specify characterization work as well as students seeking a broad understanding of the field. The tutorial examines a broad range of important properties and discusses how film thickness may cause measured values/performance to differ from bulk properties. Generic differences between counting and spectroscopic techniques are presented and available “probes” are identified.
Properties and Applications of Tribological Coatings,
Dr. Gary Doll, University of Akron and Dr. Allan Matthews, The University of Manchester
This tutorial is intended for design engineers, materials scientists, and coatings developers who have a need to specify and develop coatings for tribological (i.e., those in which wear must be reduced or prevented and/or friction minimized) and corrosion-resistant applications. The tutorial begins with the fundamentals of tribology and corrosion, and discusses the problems of selecting coatings for optimal performance. An overview of the main processes for producing coatings is given, which includes gaseous (e.g., CVD and PVD), solution (e.g., electroless and electrochemical), and molten (e.g., thermal spraying and laser treatments) state processes. Test methods used to evaluate coatings are also reviewed, which covers tests for physical and mechanical properties, tribological performance, and corrosion resistance. Finally, coatings that have been developed and utilized for some specific applications will be discussed.
