Beschreibung
Zusammenfassung:	Disclosed is an abrasion resistant material having low cost and excellent abrasion resistance, a puffer cylinder, and a puffer type gas circuit breaker. The abrasion resistant material includes: a base material which is formed of pure aluminum or aluminum alloy and has an unevenness structure formed on its surface; and an aluminum hydrated oxide film which is formed on the surface of the base material, wherein a surface of the aluminum hydrated oxide film is provided with an unevenness structure which is finer than the unevenness structure of the base material.
