Cracking the code for surface coating of gas turbines – Engineering Materials

A study at the University West (Högskolan Väst) investigated the shape and number of cracks in gas turbine coating and found that not all cracks are bad.

The surface coating used on gas turbines to increase lifespan, consists of two layers – one of metal to protect against oxidation and corrosion , and a ceramic one for thermal insulation. The structure of the coating varies, with pores and cracks of different sizes, which determine the efficiency of the thermal insulation and the length of the coating life-span. – See more at: http://www.materialsforengineering.co.uk/engineering-materials-news/cracking-the-code-for-surface-coating-of-gas-turbines/73786/?__scoop_post=97af0600-b454-11e4-93c7-842b2b775358&__scoop_topic=1472349#__scoop_post=97af0600-b454-11e4-93c7-842b2b775358&__scoop_topic=1472349
