In machine assemblies made of titanium or titanium alloys, such as turbo-compressors, where at least one rotating member is arranged directly adjacent to at least one stationary structural titanium member, the radially outer contours or surfaces of a radially inner stationary member, as viewed relative to the respective axis of rotation, are provided with a surface layer of a highly heat-conductive material. This heat-conducting layer enables the heat of friction generated when a fragment is jammed inbetween a moving and a stationary member, to be dissipated extremely rapidly over a large surface area to keep the titanium casing material from reaching the ignition temperature, whereby the ignition of titanium fires is prevented.
