Laser surface melting and re-solidification has been applied to eliminate pores and create homogeneous surfaces in refractory ceramics, improving the high-temperature degradation resistance of such materials. The major problem in laser surface treatm

Laser surface treatment of Al2O3-based refractory ceramics, by melting and re-solidification, can be successfully applied to producing surfaces that are pore-free, homogeneous and crack-free. Such treated surfaces can lead to an increase in the corro

High alumina refractory ceramics offer increased resistance in slagging environments. In particular, the presence of more than 5% Cr 2 O 3 in a high alumina refractory ceramic increases its slag corrosion resistance due to the formation of a dense Cr

Laser surface treatment of high alumina refractory ceramics has been applied successfully to produce pore-free, homogeneous and crack-free surfaces. The treated surfaces should lead to an increase in the corrosion and erosion resistance of the materi

k-Type thermocouple (NiCr–NiAl) joints are currently manufactured by argon arc welding. One of the weaknesses of this joining method is that the weld bead diameters are about three times of the thermocouple wires. This slows the response time of th

Alumina-based refractory materials are extensively used in high-temperature applications, such as linings in waste incinerators. A significant problem affecting the performance of these materials is the presence of porosity and material inhomogeneity
