Engineering Education in the US: Time for a New Look?
Dr. Bruce M. Kramer
Director, Division of Engineering Education and Centers
National Science Foundation
Engineering Schools in the US have been viewed as world innovators since the widespread adoption of engineering science-based curricula in the post-Sputnik era. These curricula expanded quickly, as graduates of forefront programs became faculty in rapidly growing and newly formed departments, energized by expanding federal research funding. Forty years later, undergraduate engineering enrollments have been flat for 10 years, domestic students increasingly shun graduate studies in engineering, and engineering skills are commodities available worldwide at low cost. These are only a few indications that we need to take a hard look at what we teach in engineering and how we teach it. It may be time for the next great wave of innovation.

- Room 173, Light Engineering
- Abstract:
  The quasicrystal has a new type of ordered structure characterized by crystallographically-disallowed rotational symmetry and by quasiperiodicity. Reflecting those peculiar structural order, quasicrystals have been shown to exhibit characteristic structural phase transitions such as quasicrystal-to-crystal approximant transition and order-disorder transition in quasicrystal. In this seminar, our recent works on those phase transitions will be reviewed after a brief introduction to the concept of the quasicrystal.

- Emerging Opportunities in
  Thermal Spray Technology
- A two-day workshop
- Registration required
- The object of this Workshop is to examine emerging opportunities in thermal spray technology. In this regard, the speakers, representing a wide range of industries, will review selected areas of applications that are rapidly growing. Consistent with the Center's central theme of linking research to practice, discussions will be presented on the supportive, fundamental studies that are aiding in an expansion of thermal spray applications. The Workshop is dedicated to the conviction that these diverse applications of thermal spray will continue to grow and, indeed, will gain increased recognition by the general engineering community. This is the third in a series of Workshops offered by the Center and sponsored in part by the National Science Foundation. The 1991 Workshop focused on the fundamentals and uses of the plasma spray process. The 1995 Workshop was dedicated to thermal spray in the manufacturing environment, and as such concentrated on processes. The 1998 Workshop will examine new and emerging applications as practiced in the automotive, marine, electronics, energy-related industries, etc. These Stony Brook Workshops differ from traditional conferences in that the focus will address the development and implementation of the technology. The objectives of the Workshop are:
  - Exploration of fresh directions in thermal spray technology.
  - The role and relevance of research in discovering opportunities for the technology.
  - Recent developments and future needs in process and control.
  - The evolution of thermal spray equipment and instrumentation.
Friday, 05-08-98, 10:00
- Prof. Joachim Heberlein
  Department of Mechanical Engineering
  University of Minnesota
- Plasma Spray Torch Characterization -
  Cathode, Anode and Turbulent Plasma Jet
- Abstract:
  Plasma torch designers have done an excellent job in torch optimization largely on a trial and error basis, and, frequently, it is left to academia to find explanations for why things work as well as they do. However, when operational reliability requirements move close to 100%, systems as complex as plasma torches with a large number of independent parameters require a sufficiently large knowledge base to assure operational stability.
  In this talk Prof. Heberlein, will review what we know about the various torch components which contribute to the generation of the plasma spray jet, and how their operation affects the spray process. In particular, he will discuss some results of thermionic cathode operation, of a stable and an unstable anode attachment, and the effects of the anode instability and the large scale turbulence on particle heating and trajectories in the jet. Some approaches to increasing plasma jet stability and more reproducible particle heating will also be presented.

- Microstructural Tailoring of Cermaics
  for Mechanical and Thermal Properties
- Room 250, Light Engineering
- Abstract:
  In the first part of this talk, various strategies will be discussed for making ceramics tough and damage tolerant through the tailoring of their macro and micro-structures. Novel methods for the in situ processing of these ceramics, in monolithic, layered and graded forms, will be presented along with a discussion of the principles of microstructural evolutions. The mechanical properties of such ceramics will also be presented along with a discussion of structure-property relations.
  The second part of this talk will pertain to thermal barrier coatings (TBCs), used to insulate and protect hot-section metal components in gas-turbine engines. The high oxygen diffusivity in the current Zr02-based TBC's, and the attendant oxidation of the metal substrate.

- Replacement of Chromium Electroplating
  Using HVOF Thermal Spray Coatings in Aircraft Maintenance:
  Comparative Studies and Technology Insertion
- Hard chrome plating is a critical process associated with maintenance activities at all Department of Defense (DOD) aircraft and ground vehicle depots and Naval shipyards, but it utilizes chromium in the hexavalent state (hex-Cr) which is a known carcinogen and which is highly regulated by the EPA and OSHA. Due to environmental and associated increasing cost concerns, the DOD established a program to qualify HVOF thermal spray coatings as viable alternatives to hard chrome plating in aircraft maintenance. The project team, designated the Hard Chrome Alternatives Team (HCAT) and consisting of DOD and university laboratories, DOD aircraft maintenance depots and private industry, has established a Joint Test Plan (JTP) to delineate the types of tests required to execute this qualification and successfully validate HVOF coatings on flight-critical components. The JTP includes fatigue, corrosion, wear, and mechanical properties evaluations on 83/17 WC/Co and Tribaloy 400 HVOF coatings as compared to hard-chrome, with results for some of these tests already having been obtained. This presentation will focus on the issues associated with hard-chrome replacement, describe the results of the comparative testing, and discuss plans for flight testing of HVOF-coated components and insertion of the technology at the depots.
