The purpose of the present invention is to provide a charged particle beam device that exhibits high performance due to the use of vanadium glass coatings, and to provide a method of manufacturing a component for a charged particle beam device. Specifically provided is a charged particle beam device using a vacuum component characterized by comprising a metal container, the interior space of which is evacuated to form a high vacuum, and coating layers formed on the surface on the interior space-side of the metal container, wherein the coating layers are vanadium-containing glass, which is to say an amorphous substance. Coating vanadium glass onto walls of a space where it is desirable to form a high vacuum, for example walls in the vicinity of an electron source, reduces gas discharge in the vicinity of the electron source, and the getter effect of the coating layer induces localized evacuation and enables the formation of an extremely high vacuum, even in spaces having a complex structure, without providing a large high-vacuum pump.
摘要:
A glass lined reaction tank for chemical and pharmaceutical industries and a manufacturing method thereof. One-step molding technical standards for manufacturing iron blanks of the glass lined reaction tanks are deeply developed, an overall structure of a flanged big flange of a tank body and a tank cover matching with the tank body are innovated, and nominal pressure of the big flange and the sealing performance of a tank mouth are perfectly improved. By using a new structurally-combined precise controlled internal heating type electric furnace and an intelligent temperature program control/adjustment/recording instrument, heating temperature of an overall glass lining layer on an inner wall of the tank body is more accurately controlled to be the same, and a synchronous, integral and controlled sintering core technique is realized.

摘要:
Applicants have disclosed a process for fusing a biocompatible glass to a metal substrate. In the preferred embodiment, the process comprises: grit blasting a metallic substrate (e.g., titanium) to remove a surface layer of the metal; after blasting, cleaning the abrasion residue off the surface layer; blending a solvent to use as a suspension agent; creating a suspension of glass-coating powders in the solvent solution; depositing the suspension onto the metallic substrate; drying thoroughly the suspension-coated metallic substrate; inserting the dried, coated substrate into a non-reactive chamber, purging the chamber with an inert gas, such as pure argon; and firing the metallic substrate, inside the furnace, in the inert gas. This process forms a robust fusion between the biocompatible glass/ceramic and titanium, according to preliminary test results. This process can be used for various medical and dental devices, including implants and onplants.
