Low Wear materials

Tribological requirements for contacting materials

• No seizure (blocking of joint by too strong interfacial adhesion). Ti alloys and austenitic stainless steels therefore excluded!

• High resistance against

scratching. -

^ high hardness

• High resistance against fatigue

and impacts-

^ high toughness
