Abstract

A kind of surface treatment method of titanium or titanium alloy section bar cold stretch is related to a kind of surface treatment method of metal stock before metal cold working, more particularly to a kind of surface treatment method for metal stock in titanium or titanium alloy production pipe, stick, silk cold stretch.The present invention is after with physical method to the cleaning on metal stock surface, metal stock surface is made to form one layer of modified cover film through liquid leaching, then the coating solid lubricant outside modified cover film.The lubricant that the present invention obtains have is firmly combined with base material, stretch friction coefficient it is low, it is wear-resisting the advantages of, it can continuous multimode, the low titanium alloy of aximal deformation value cold working high intensity, plasticity, sticking to mould, demoulding phenomenon does not occur, while lubricant easily removes after processing during cold working.

Description

A kind of surface treatment method of titanium or titanium alloy section bar cold stretch
Technical field
A kind of surface treatment method of titanium or titanium alloy section bar cold stretch is related to metal stock before a kind of metal is cold worked Surface treatment method, more particularly to it is a kind of for titanium or titanium alloy production pipe, stick, silk stretch process in metal stock table Surface treatment method.
Background technology
Since metal titanium or titanium alloy has the characteristics that high intensity, corrosion-resistant, low-density, and be widely used in military project, aerospace, Petrochemical industry and field of metallurgy, but titanium alloy resistance of deformation is big, plasticity is low, is difficult to process.During titanium shape extrusion, Adherent phenomenon easily occurs, influences section bar surface quality.It therefore, must be first attached to blank progress surface to titanium shape extrusion Put forth effort to handle, then apply lubricant, prevent from adhering in titanium shape extrusion, reduce coefficient of friction, increase wearability.Generally to titanium-type Material blank surface lubricated is typically to use to carry out blank air heating to form oxidation film, also has and is plated in blank surface Copper also coats fluorinated phosphate salt coating in blank surface.It was verified that titanium-type material is cold worked, particularly to deformation The TC that drag is big, plasticity is low4Titanium alloy is difficult to realize.Therefore, it can only be used at present and hot-working or swaged, processing efficiency and Lumber recovery is relatively low.
Invention content
During the purpose of the present invention is aiming at above-mentioned existing titanium or titanium alloy cold working, existing surface treatment The deficiency of method, provide it is a kind of effectively titanium or titanium alloy blank surface can be handled, effectively prevent from adhering to, reduce friction Coefficient increases wearability, and the surface treatment side of a kind of titanium or titanium alloy section bar cold stretch that lubricant easily removes after processing Method.
The purpose of the present invention is what is be achieved through the following technical solutions.
A kind of surface treatment method of titanium or titanium alloy section bar cold stretch, including with physical method to metal stock surface Cleaning, it is characterised in that：A. the metal stock after cleaning is immersed in modification liquid, its surface is made to form one layer of modified covering Film, the main ingredient of film is Na3TiOF5；B. the blank of one layer of modified cover film of surface band is pulled out airing；C. it will contain 85% (weight ratio) S-O aquadags, 5%MoS2With kollag behind 10% water ground, it is equably coated in modified treated blank Surface dries at a temperature of 200-300 DEG C and treats that cold stretch is used.
By titanium or titanium alloy blank carry out surface modification treatment liquid composition be：
Na3PO4.12H2O：30g/l-50g/l,
NaF：20g/l-40g/l,
Ice CH3COOH (36%)：50g/l-70g/l.
Compared with the prior art the present invention, there is lubricant to be firmly combined with base material, stretching coefficient of friction is low, wear-resisting epistasis The advantages of, can continuous multimode, the low titanium alloy of aximal deformation value cold working high intensity plasticity do not glue during cold working Film demoulds phenomenon, while lubricant easily removes after processing.
Embodiment：
Select two kinds of TC of thickness of  4.6mm and  2.1mm4(Ti-6Ai-4V) wire rod is intended to the above-mentioned wire rod physics of cold working Method clears up behind its surface to be put into：Na3PO4.12H2O：30g/l-50g/l, NaF：20g/l-40g/l, ice CH3COOH (36%)：In the surface modification treatment liquid that 50g/l-70g/l is made into, its wire surface is made to form one layer of modified covering Then film pulls the above-mentioned wire rod of one layer of modified cover film of surface band out airing, be then uniformly coated on modified cover film Contain 85% (weight ratio) S-O aquadags, 5%MoS2With the rear kollag of 10% water, and at a temperature of 200~300 DEG C After continuous three mould and five mould cold stretch, two kinds of TC of  3.1mm and  1.2mm are made in drying respectively4Silk.Accumulative working modulus is equal More than 65%, wherein, maximum passage processing capacity is up to 32%, during entire cold stretch, does not occur sticking to mould, demoulds and break Phenomenon, silk surface quality after stretching with it is functional.
The present invention, the TA of 14.6 × 2.2mm of processing  are similarly used the cold stretch of the tube, rod section material of titanium or titanium alloy2 Tubing, for maximum passage processing capacity up to 40%, it is more than 75% to add up processing capacity.
