| Popis: | The effect of temperature and elemental concentrations of phosphorous, sulphur and titanium in high alloyed Cr-Mn-Ni TRIP/TWIP steels (16 %Cr, 7 %Mn, 6 % Ni) on the wettability of MgO partially stabilized zirconia (Mg-PSZ) substrates was studied. The investigation of the wetting behavior is of a major importance of the infiltration of steel into open foam ceramics and in interfacial contact of steel & ceramic powder in the spark plasma sintering. The interfacial reaction was characterized using X-ray and secondary neutral mass spectrometry analysis. The contact angle was investigated between 1500 ℃ and 1600 ℃ in argon (99.999 vol% Ar) atmosphere and was found to decrease with increasing temperature. At 1600 ℃ sulphur decreased the contact angle from 103 ° (100 ppm S) to 92 ° (1000 ppm S) in Fe-Cr-Mn-Ni. Increasing phosphorous content was found to increase the interfacial oxygen content in samples and the contact angle decreased to ca. 97 °. For titanium alloyed Cr-Mn-Ni sample, a TixOy interfacial layer was found after experiments and the contact angle was ca. 87 ° at maximum Ti content of 0.232 %. |
