Disclosed is a method of manufacturing an assembly of components joined by brazing, comprising the steps of:(i) forming the components of which at least one is made from a multi-layered brazing sheet product, the multi-layered brazing sheet product comprising a core sheet (a) having on at least one surface of the core sheet an aluminium clad layer (b), the aluminium clad layer being made of an aluminium alloy comprising silicon in an amount in the range of 2 to 18% by weight, a layer (c) comprising nickel on the outer surface of the aluminium clad layer, and a layer (d) comprising zinc or tin as a bonding layer between the outer surface of the aluminium clad layer and the layer comprising nickel;(ii) forming at least one other component of a metal dissimilar to the core sheet of the multi-layered brazing sheet product and selected from the group consisting of titanium, plated titanium, coated titanium, bronze, brass, stainless steel, plated stainless steel, coated stainless steel, low-carbon steel, plated low-carbon steel, coated low-carbon steel, high-strength steel, coated high-strength steel, and plated high-strength steel;(iii) assembling the respective components into an assembly such that the layer (c) comprising nickel of the multi-layered brazing sheet product faces in part or in whole the at least one other component of a metal dissimilar to the core sheet of the multi-layered brazing sheet product;(iv) brazing the assembly under a vacuum or in an inert atmosphere in the absence of a brazing-flux at elevated temperature for a period long enough for melting and spreading of the aluminium clad layer and all layers exterior thereto;(v) cooling the brazed assembly.The invention further relates to an assembly manufactured using the method of this invention.

The present invention relates to a method for the preparation of a biocompatible metal ion-containing titanium oxide coating on an implant wherein the metal ions can be eluted under physiological conditions and are homogeneously dispersed within the coating, as well as to an implant which can be prepared according to the method of the present invention.

The invention discloses a lithium ion battery positive electrode material aluminum-titanium coating preparation method comprising the steps that: nickel salt, manganese salt, a cobalt salt solution and a sodium hydroxide solution containing ammonia water are introduced into a reaction container, and a precipitation reaction is carried out; a hydroxide precursor M containing nickel-manganese-cobalt and lithium salt are mixed according to a molar ratio of 1.0-1.2; the mixture is calcined, cooled, crushed, and sieved, such that the lithium ion battery positive electrode material is obtained; the obtained material is prepared into slurry and is introduced into a well dispersed mixed solution of alumina and titania, and a reaction is carried out; the material obtained after the reaction is subjected to solid-liquid separation, and is washed by using deionized water; and bake-drying and sintering are carried out, such that an aluminum-titanium-coated lithium ion battery positive electrode material is obtained. With the method disclosed by the invention, high-manganese ternary positive electrode material processing performance and tap density are improved, and material capacity and stability defects are overcome. Through controlling precursor morphology and particle size, physiochemical performances of the high-manganese ternary positive electrode material can be controlled, and material stability is improved.
