Abstract
In the course of technological operations and the following running, the aluminum nanolayer providing reliable unglue bonding the ZERODUR parts demonstrates a complex of previously unknown properties: - compensation of small geometrical deviations in joined parts, due to aluminum plasticity the requirements to geometry of joined parts can be lowered from Ν = 0.5, ΔΝ = 0.1 (where Ν is the deviation of surface geometry from standard expressed in the Newton interferential rings, ΔΝ – local error or deviation of the type “well” or “nib”), which are necessary for joining, if one applies the methods of optical contact or deep optical contact, to Ν = 2-5, ΔΝ = 1; - Chemical interaction with polished ZERODUR surface at relatively low temperatures (400 to 600ºС); - Minimum level of internal mechanical strains in joined parts; - Properties of elastically-brittle durable material. Using the above generalization of the obtained results, we have offered new technological schemes for production of ZERODUR parts with a complex shape.
