Thermal Spray Technology

Course Overview:

Thermal spray technology and coatings solve critical problems in demanding environments. They provide “solutions” to problems involving repair, wear, high temperature and aqueous corrosion, and thermal protection. Thermal spray can also be used to manufacture net-shapes, advanced sensors and materials for the biomedical and energy/environmental sectors. These and other emerging applications take advantage of the rapid and cost-effective capabilities of thermal spray technology in the OEM and repair industries.

Thermal spray processes - twin wire-arc, combustion, high velocity oxy-fuel (HVOF), cold spray and plasma spray, and associated technologies, can deposit virtually any material as a surface coating onto a wide range of other materials. Coating reliability and effectiveness requires that these overlay coatings be selected, engineered and applied correctly.

This course

(i) provides a thorough grounding and understanding of thermal spray processes,
(ii) presents the complex scientific concepts in terms of simple physical models, and
(iii) integrates this knowledge to practical applications and accepted thermal spray practices. NO mathematics is used to explain the processes or materials/mechanical engineering.

Learning Objectives

Upon completion of this course, participants will:

Understand the historical basis for thermal spray technology and have detailed knowledge regarding the development of equipment and materials as related to present-day technology.

  • Recognize the terminology, principles and underlying theory of thermal spray technology.
  • Compare and contrast thermal spray technologies with respect to competing coating technologies - PVD, CVD, hardfacing, electroplating etc.
  • Explain how feedstocks are designed and manufactured and how to select them for different spray processes.
  • Identify applicable testing methods and currently accepted industrial practices used for quality control of coatings.
