A wear-resistant alloy is inlaid in a channel along the undersurface of a cutting edge of a ground-engaging implement. The wear-resistant alloy is in the form of individual blocks which are brazed within the channel. The joints between contiguous blocks are non-parallel to the general direction of travel of the ground-engaging implement for improved tool wear.

Ground-engaging tool inserts with angled edges

Spheroidal particles of wear-resistant alloy comprising boron, chromium and iron having maximum hardness for a given composition are produced by the rapid cooling of a molten alloy mixture. The resultant solid particles are then incorporated into a composite alloy wherein the solid particles are held together with a matrix of different material from the alloy. Inserts of the composite wear-resistant alloy are useful in producing long wearing tools.

Composite wear-resistant alloy, and tools from same

A wear-resistant composite material and method of making an article thereof is disclosed which is particularly adaptable for use with a ground-engaging tool. The composite material has a plurality of abrasive-resistant particles embedded in an iron-boron matrix.

Wear-resistant composite material and method of making an article thereof

A ground-engaging tool is disclosed which includes a blade with a load carrying front face, a ground-engaging bottom surface, and a rear face, and a wear-resistant insert is secured thereto to extend the service life thereof. The wear-resistant insert includes a back-up plate which is disposed in rearwardly spaced relation from the rear face of the blade and adjacent its bottom surface, a wear-resistant material which is bondably sandwiched between the plate and the rear face, and a plurality of bridging members which extend through the wear-resistant material and are rigidly secured to the plate and the rear face of the blade to minimize in use spalling of the wear-resistant material.
