Abstract

The invention relates to vacuum coating experimental equipment, specifically a high-temperature and high-vacuum annealing furnace, in which an ion pump, an annealing chamber cavity, a sampling chamber cavity, and a molecular pump are connected in sequence, and the molecular pump is connected to a mechanical pump through a pipeline. Between the pump and the cavity of the annealing chamber, between the cavity of the annealing chamber and the cavity of the sampling chamber, and between the cavity of the sampling chamber and the molecular pump, there are flap valves; the cavity of the annealing chamber is equipped with a fixed upper heater And the lower heater that can be lifted up and down, the cavity of the sampling chamber is equipped with a multi-layer sample library that can be lifted up and down, and a manual transfer rod manipulator is installed on one side of the cavity of the sampling chamber. The invention can quickly complete the sample exchange with the annealing chamber under vacuum conditions, ensuring that the annealing chamber is always in a high vacuum state. In the high-temperature and high-vacuum annealing furnace of the present invention, the cold-state ultimate vacuum degree of the annealing chamber can reach 10 ‑8 Pa ultra-high vacuum, when heated at 1600°C, the thermal vacuum degree can reach 10 ‑ 6 Pa, and it can realize the long-term heat preservation annealing of the sample not higher than 1600 °C.

Description

technical field [0001] The invention relates to vacuum coating experimental equipment, in particular to a high-temperature and high-vacuum annealing furnace. Background technique [0002] Annealing is a common process for heat treatment of vacuum coating experimental equipment. The technical problems existing in the current vacuum annealing furnace are: [0003] 1. The vacuum degree of the existing vacuum annealing furnace is low and cannot provide a very clean process environment. [0004] 2. The temperature of the existing vacuum annealing furnace is not high, and it is difficult to achieve high temperature and long-term heat preservation. [0005] 3. The temperature uniformity of the sample annealing is not good. SUMMARY OF THE INVENTION [0006] In view of the above problems existing in the existing vacuum annealing furnace, the purpose of the present invention is to provide a high temperature and high vacuum annealing furnace. The cold limit vacuum degree of the a...
