description A method of fabricating a PCD cutter element including a diamond table including a plurality of coated diamond particles fabricated using an atomic layer deposition (ALD) process. The method for fabricating a PCD cutter element, comprises: (a) coating, by atomic layer deposition (ALD), a plurality of diamond particles by directly depositing the coating on an outer surface of each diamond particle of the plurality of diamond particles to form a plurality of coated diamond particles; (b) removing oxides from the plurality of coated diamond particles after (a); and (c) forming a PCD cutter element using the coated diamond particles after (b), such that the PCD cutter element has an outermost layer of uncoated diamond particles and the plurality of coated diamond particles are disposed within the outer most layer of uncoated diamond particles.
