Abstract
The invention provides a porcelain tooth and preparation method thereof. The porcelain tooth is prepared from the following raw materials by weight: 18 parts of nickel, 6 parts of boron, 4 parts of niobium, 6 parts of carbon, 3 parts of chromium, 7 parts of titanium, 8 parts of aluminum, 3 parts of cerium, 6 parts of molybdenum, 4 parts of tungsten, 5 parts of manganese and 7 parts of silicon. The preparation method comprises the following steps: filling a high temperature ceramic crucible with the above-mentioned chemical components and carrying out heating and fusing in a vacuum intermediate-frequency or high-frequency furnace; stirring high-temperature melt for 5 to 10 s; then casting the uniformly stirred melt into a square die or a cylindrical die; carrying out natural cooling to form an ingot; subjecting the ingot to sandblasting so as to remove substances adhering on the surface of the ingot; and polishing the ingot so as to obtain a cobalt-chromium-based alloy for the porcelain tooth. The zirconia sintered whole porcelain tooth provided by the invention is simple to prepare, has small shrinkage in sintering, high flexural strength, good sealing performance of restoration, high biocompatibility and a low price, 2% of the price of overseas porcelain teeth, is suitable for the national condition of China and can be easily promoted.
Description
Technical field
The present invention relates to a kind of technology of alloy material, particularly a kind of for baking-ceramic tooth nickel chromio-based alloy and preparation method thereof.
Background technology
Porcelain is a kind of dentistry, is generally referred to as baking-ceramic tooth.This dummy has the verisimilitude of the high strength of metal, the aesthetic property of porcelain and tooth, and the advantage such as wear-resisting, to the labial teeth of disappearance and the reparation of backteeth, can reach desirable function, the form of repairing agomphosis.
Summary of the invention
The object of this invention is to provide a kind of High anti bending strength, sintering shrinkage is little, and dummy adaptation is good, and good biocompatibility is easy and simple to handle, cheap a kind of baking-ceramic tooth and preparation method thereof.
The technical solution used in the present invention is:
A kind of baking-ceramic tooth, is made up of the raw material of following parts by weight: nickel 15-20 part, boron 4-9 part, niobium 2-6 part, carbon 4-8 part, chromium 2-6 part, titanium 5-10 part, aluminium 5-10 part, cerium 1-7 part, molybdenum 4-8 part, tungsten 3-6 part, copper 2-8 part, manganese 3-6 part, silicon 5-10 part.
A kind of baking-ceramic tooth and preparation method thereof: the batching of above-mentioned chemical composition to be loaded in high-temperature ceramic copple and in a vacuum frequently or high frequency furnace heat fused, high temperature melting liquid is stirred 5-10 second, the melt stirred is cast in square dies or cylindrical die, ingot bar is formed after naturally cooling, ingot bar is removed its surface attachments through sandblasting, finally ingot bar polishing is just become baking-ceramic tooth cobalt croloy.
Zirconium oxide sintering pure porcelain teeth method of the present invention is easy, and sintering shrinkage is little, High anti bending strength, and dummy adaptation is good, good biocompatibility, low cost, is only 2% of foreign country, is applicable to China's national situation, easily popularizes.
Embodiment
