Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a CMC_LPT blade and a blade tip shroud which lower or prevent loss of CMC material and prevent reduction and possible loss of interlock load between adjacent blade tip shrouds, and possible sealing issues.SOLUTION: A ceramic shroud assembly 99 includes a tip shroud 88 having an outer platform 86 supporting a seal tooth 91, a shroud cap 96 less brittle than the outer platform and including a shroud cap base on the outer platform, and a contact surface. A rotor assembly may include a circumferential row of turbine blades 70 made of a ceramic material and extending radially outwardly from a disk of a turbine rotor. The shroud 88 and the platform 86 may be made of a ceramic or ceramic matrix composite material and the shroud cap 96 may be made of a metal material.
