Abstract
A wear component for use on, for instance, an excavator formed by a shell formed from a tough metal such as carbon steel and an inner body formed from an abrasion resistant metal such as a chromium white iron. The shell includes cross portions extending through the inner body, the cross portions being made of the tough metal. This has the effect of strengthening the overall toughness of the wear component, whilst retaining desirable abrasion resistance.
Claims26
A wear component formed from at least a first metallic material and a second metallic material, the first material having a toughness greater than that of the second material and the second material being more abrasion resistant than the first material;
- the wear component having a shell formed from the first material and an inner body formed from the second material, a metallurgical bond existing between the first material and the second material;
- wherein the shell includes at least one cross portion extending through the inner body, the cross portion being formed from the first material and having a first side and a second side each of which are bonded to the second material.
A wear component including:
- an inner face for attachment to apparatus subject to wear, the attachment defining a protected surface portion of the apparatus;
- and
- an outer face which is exposed, in use, to abrasive wear;
- a volume being defined between the protected surface portion of the apparatus and the outer face of the wear component representing the effective volume of the wear component;
- wherein a portion of this volume contains a void.
