Increasing Temperature Capability

Abstract

Fundamental requirements in increasing temperature capability include increase in strength at high temperature and increase in environmental resistance. However, the measures adopted to increase strength may be detrimental in terms of environmental resistance. Thus in many cases the overall design requirement cannot be satisfied by a single material. Coatings are commonly required. Depending on the complexity of component duty it may be necessary, in extreme cases, to apply multiple coatings to protect against different environmental factors, for example, corrosion and wear.
