摘要：

Abstract—The temperature dependence of the Ti–18Zr–15Nb alloy dilation in an ultrafine-grained (UFG) state formed by equal-channel angular pressing (ECAP), which is coated using plasma-electrolytic oxidation (PEO), is investigated. The stability of the formed PEO coatings to heating and cooling has also been determined. The results demonstrate that a sharp increase in the thermal expansion coefficient (TEC) at 350°C indicates the presence of a phase transformation. During tests, a porous coating on the Ti–18Zr–15Nb alloy is retained, but cracks become larger and longer.
