Thermal equilibrium means “Temperature gradient is zero”.
-Suppose we have metal bar and is heated and then we keep it our in room (room temperature).
-After sometime the bar will have same temperature at every point on it.
-There is no gradient of temperature , No heat exchange between bar and surrounding.
