Laser induced high temperature thermal-mechanical-oxygen coupling experimental system and method

In this paper, a thermal–mechanical–oxidation coupling experimental system based on laser heating is developed, containing two modes of Gaussian and flat-top lasers, which has series advantages such as high temperature range, rapid rate, convenient observation. The adopts active illumination an optical filter to solve the problem where it difficult for traditional digital-image correlation technology image clearly under heating. A biaxial mechanical test machine used simulate complex load by applying tension or compression loads material. Combined with radiation measurement controllable flow field device, thermal-mechanical-oxygen experiment resistant materials aerobic environment can be carried out. maximum uniform heat flux output density 27.2 kW/cm2, 105 kW/cm2. method are great significance development new thermal barrier coatings.
