The working environment of agricultural cutting tools is poor, and the operational quality and efficiency are reduced after they become blunt. This study aimed to develop a high wear-resistant agriculture knife with a long life. A Ni–WC alloy, wear-resistant layer was prepared using laser cladding technology on one side of the cutting edge of a 65 Mn silage knife. A self …
Manganese, a gray-white metal, is used extensively in steelmaking. The element's desulfurizing and deoxidizing properties make it a key ingredient in the making of steel and other alloys. Metal fabricators should be aware of the dangers of overexposure to manganese because the element is prevalent in their work environment.
A large number of natural aggregates are used in the field of construction materials, resulting in the exhaustion of natural aggregates. Therefore, looking for an alternative will slow down the consumption of natural aggregates.

The currently proposed mineral processing operations are based on metallurgical approaches applied for land resources. Thus far, significant …
Manganese promotes work-hardening so you have to use a pretty hard grade. Cermet in general will outperform carbide, but cermets vary greatly in quality, which is apparently a function of ceramic material purity. We have been able to run relatively inexpensive cermets (TN60 grade) dry in both milling and turning applications at 30 times ...
