Despite environmental concerns, the automotive, aerospace and other manufacturing industries still extensively use hard-chrome coatings. This is mainly due to the coatings' ability to combine unmatched aesthetics with high hardness, excellent wear resistance, low friction and good corrosion protection in aggressive environments. However, the performance of hard-chrome coatings is dependent on the...
In the present work the friction and anti-galling properties of the h-BN in a steel-aluminium contact have been investigated, focusing on the possibility of replacing graphite with the h-BN in the aluminium forming operations. Extruded AA2014 alloy, widely used for the production of complex parts, was used. Investigation included the effect of h-BN powder size and concentration on the level and stability...
With the introduction of modern low-weight high-strength materials, tools and dies in hot metal forming are exposed to increasingly demanding contact conditions. This requires use of surface engineering techniques and proper balance between core hardness and fracture toughness. However, it is not very straight forward which combination to use in terms of wear resistance. The aim of this work was to...
