Abstract

The invention discloses a novel titanium alloy composite tube which is characterized by comprising a titanium alloy layer and an auxiliary layer, wherein the auxiliary layer is located in the titanium alloy layer, and a separation layer is arranged between the titanium alloy layer and the auxiliary layer. The improved titanium alloy layer is made of titanium alloy and has the thickness of 0.5-2.5cm. The auxiliary layer is made of stainless steel materials. The separation layer is made of polyethylene materials. The stainless steel auxiliary layer is arranged in the titanium alloy tube and the separation layer made of polyethylene materials is arranged between the titanium alloy tube and the stainless steel auxiliary layer so that the mass of the titanium alloy composite tube is reduced, the property of titanium alloy is kept, and the problem that titanium alloy is difficult to process is solved. The novel titanium alloy composite tube is low in cost due to the fact that the mass of the composite tube is reduced by about 40% compared with the pure titanium alloy tube, and simultaneously service life of the novel titanium alloy composite tube is ensured due to the fact that the composite tube does not rust.

Description

technical field

[0001] The invention belongs to the field of titanium alloy pipes, and in particular relates to a novel titanium alloy composite pipe. Background technique

[0002] In bicycle and other fields, titanium alloy is widely used due to its superior performance. However, the plasticity of titanium alloy is much worse than that of other materials. It is difficult to make many styles of handlebars like aluminum alloy and chrome-manganese steel. Although the required shape can be processed by traditional processing technology, the processed products are difficult to meet the processing requirements, mainly because the product quality is not stable, and the quality is heavy, which increases the overall weight of the bicycle and affects the use of the bicycle. Not conducive to marketing. Contents of the invention

[0003] The technical problem to be solved by the present invention is to overcome the above defects and provide a new titanium alloy composite pipe with l...

Examples

Embodiment

[0019] Such as figure 1 As shown, a new titanium alloy composite pipe includes a titanium alloy layer 1 and an auxiliary layer 3 , and the auxiliary layer 3 is located in the titanium alloy layer 1 . An isolation layer 3 is arranged between the titanium alloy layer 1 and the auxiliary layer 2 .

[0020] In this embodiment, the titanium alloy layer 1 is made of titanium alloy with a thickness of 0.5-2.5 cm, and the outer diameter of the titanium alloy layer is 8-12 cm.

[0021] In this embodiment, the auxiliary layer 2 is an auxiliary layer made of stainless steel. Meanwhile, the outer diameter of the auxiliary layer is 6-10 cm, and the thickness of the auxiliary layer is 1-2 cm.

[0022] In this embodiment, the isolation layer 3 is an isolation layer made of polyethylene material. The thickness of the isolation layer is 2-4cm.

[0023] In order to better achieve the predetermined effect, the cross-sectional shape of the titanium alloy layer 1 and the auxiliary layer 3 is ci...
