Abstract

The invention relates to the technical field of sintering, and particularly discloses a semiconductor glaze layer sintering method for improving the matching degree of a semiconductor part and a central electrode, which is used for sintering a semiconductor glaze layer on a porcelain tube, and is characterized by comprising the following steps of: manufacturing a central electrode wax mold according to the shape and size of the central electrode, and matching the porcelain tube with the central electrode wax mold; and injecting pre-prepared semiconductor enamel into a contact gap between the outer conical surface of the central electrode and the inner conical surface of the porcelain tube, and after the semiconductor enamel is naturally cooled, putting the semiconductor enamel into a furnace for heating and sintering. According to the semiconductor glaze layer sintered by the semiconductor glaze layer sintering method, the matching degree of the semiconductor part and the central electrode can be improved, so that the increase of insulation resistance between the central electrode and the semiconductor part due to poor matching degree of the central electrode and the semiconductor part is avoided, and the ignition performance of the sparking plug is improved.

Description

technical field

[0001] The invention relates to the technical field of sintering, in particular to a method for sintering a semiconductor glaze layer to improve the matching degree between a semiconductor component and a central electrode. Background technique

[0002] The aircraft engine ignition system relies on the high-energy pulsating voltage emitted from the ignition device, which is transmitted to the center electrode of the ignition nozzle through the ignition cable, and the center electrode of the ignition nozzle discharges to the side electrode through the semiconductor component, breakdown the surrounding air, and generates high-energy electricity. The spark ignites the fuel-air mixture in the engine, thus starting the aeroengine.

[0003] The degree of cooperation between the center electrode and the semiconductor components is an important factor affecting the discharge performance of the nozzle. When the center electrode and the semiconductor components have a ...

Embodiment 1

[0024] The semiconductor glaze layer 300 sintering method for improving the matching degree of the semiconductor component and the central electrode is to firstly make the central electrode wax mold 200 according to the shape and size of the central electrode, then fit the porcelain tube 100 with the central electrode wax mold 200, and connect the outer cone surface of the central electrode with the central electrode wax mold 200. The pre-configured semiconductor enamel is injected into the interstices of the inner conical surfaces of the porcelain tube 100. After the semiconductor enamel cools naturally, it is placed on the high-alumina tiles, and the high-alumina tiles placed on the porcelain tube 100 are placed on the high-alumina tiles at a rate of one piece every 15 minutes. The aluminum tiles are sent into a high temperature furnace for sintering.
