| Abstract: | The effect of compositions gradient on the thermal shock resistance properties of Ti Al N functional gradient coatings has been investigated. It is shown that the thermal shock resistance properties of Ti Al N functional gradient coatings is better than that of uniform coatings and that the thermal shock resistance of Ti Al N functional gradient coatings increases with increasing the composition gradient. The coefficient of liner thermal expansion of functional gradient coatings decreases gradually from substrate to surface. |
