Tolerance ring and assembly

An assembly comprising:

• a heat generating inner member;
• an outer member;
• and
• a tolerance ring disposed between inner member and outer member, wherein the tolerance ring comprises a plurality of projections protruding radially inward or radially outward, wherein the tolerance ring comprises:
• a substrate, and
• an overlying layer comprising a thermal enhancement layer and a retention layer, the thermal enhancement layer comprising at least one of i) Vickers hardness <400 VPN or ii) a thermal conductivity >100 W/m*K, the tolerance ring being adapted to provide thermal transfer between the inner member and the outer member, wherein the thermal enhancement layer comprises a plurality of discrete projections protruding radially inward or radially outward, and wherein the thermal enhancement layer defines a portion of an exterior surface of the tolerance ring, wherein the thermal enhancement layer comprises a metal comprising at least one of aluminum, zinc, beryllium, magnesium, tin, titanium, tungsten, iron, bronze, or alloys thereof, wherein at least one of the plurality of projections is a self-contained, discrete structure.
