Abstract

An effective method for increasing the strength of fixation of hard-alloy drill bit roller cutters is developed; it consists in the use of galvanic coatings of mating parts. The strengths of the joints with three types of coatings are experimentally studied. Recommendations are developed for the type and thickness of the coatings of the parts of interference fit joints of hard-alloy bits with the mobile elements of drilling tool.
