Abstract

A high-strength ceramic laminated tube comprising an inner tube of ceramic material and at least one outer tube of a metal or ceramic material shrunken onto the inner tube is provided, e.g., a ceramic tube capable of withstanding the mechanical stresses which occur in, e.g., a gun barrel, or in a bearing subjected to great stress.
