preparation example Construction

[0049] The invention provides a preparation method of pure titanium plate, comprising the following steps:

[0050] 1) Under vacuum conditions, the pure titanium plate raw material is subjected to the first heating and holding step and the second heating and holding step, and then subjected to rapid air-cooling and quenching treatment to obtain pure titanium with a scaly crystal flower apparent structure on the surface. plate;

[0051] The holding temperature of the second heating and holding is greater than 950°C and less than or equal to 1050°C;

[0052] The size of the scaly crystal flower is 0.5-3 mm.

[0053] In the present invention, the holding temperature of the second heating and holding is greater than 950°C and less than or equal to 1050°C, more preferably greater than or equal to 970°C and less than or equal to 1030°C, more preferably greater than or equal to 990°C and less than or equal to 1010°C .

[0054] In the present invention, the size of the scaly crysta...

Embodiment 1

[0105] Using 0.8mm TA1 plate, through cutting, stretching and trimming, a cup body with a diameter of 80mm and a depth of 160mm is made. Put the titanium cup into a vacuum furnace and vacuum to 2.0×10 -3 Pa, heat up to 600°C, hold for 1 hour; heat up to 1000°C for 1 hour; then rush into argon for rapid cooling, the pressure of argon blowing is 0.2MPa, and then cool to 840°C with the furnace; finally, metallic luster is obtained The scale-like crystal flower, wherein the crystal flower size is 0.8 ~ 1.5mm.

Embodiment 2

[0107] Using 0.8mm TA1 plate, through blanking, punching and trimming, a rectangular disc-shaped product with a length of 300mm and a width of 160mm is made. Put the titanium plate into a vacuum furnace and vacuum to 2.0×10 -3 Pa, heat up to 600°C, hold for 1 hour; heat up to 1000°C for 1 hour; then rush into argon for rapid cooling, the argon air pressure is 0.2MPa, and then cool to 840°C with the furnace; finally, metallic luster is obtained The scale-like crystal flower, wherein the crystal flower size is 0.8 ~ 1.5mm.

Abstract

The invention provides a preparation method of a pure titanium plate, which comprises the following steps: under a vacuum condition, carrying out a first heating and heat preservation step and a second heating and heat preservation step on a pure titanium plate raw material, and then carrying out rapid air-blast quenching treatment to obtain the pure titanium plate with a scaly crystal flower apparent structure on the surface, the heat preservation temperature of the second heating and heat preservation is greater than 950 DEG C and less than or equal to 1050 DEG C; the size of the scaly crystal flowers ranges from 0.5 mm to 3 mm. The crystal pattern surface of the pure titanium sheet has the characteristics of high smoothness, strong anti-pollution capability, no blackening after a long time and strong oxidation resistance. And a metal crystal structure on the surface of the titanium sheet is not changed and is a low-temperature stable phase alpha-Ti. In addition, the processed titanium material surface micropores are small in aperture, the number is reduced, and the structure is more compact. The method has the characteristics of being simple in process, low in cost, high in crystal peanut forming speed, uniform in size, easy to operate and capable of being applied to a large-scale industrial production line.

Description

technical field [0001] The invention belongs to the technical field of surface heat treatment of pure titanium sheets, relates to a preparation method of pure titanium sheets, and in particular relates to a method for processing crystal flowers on the surface of pure titanium sheets. Background technique [0002] The surface of the pure titanium metal sheet is the natural color of the metal, and the appearance is too simple, which has a great restriction on the application of titanium sheet products. With the increasing consumer demand for titanium products, the surface of titanium products is also in urgent need of diversification . In addition, with the surface oxidation of titanium products with natural metal color, blackening defects appear. The crystal flower treatment on the surface of the titanium sheet can not only make the titanium products more beautiful, but also solve the defects of blackening on the surface of the titanium products. [0003] Some improved solu...
