摘要:
The invention relates to a method for passivating a surface (25) of a metal part (3), wherein a calcium phosphate-containing conversion coating (5) that comprises oxides and hydroxides as well as carbonates of the material from the metal part, is created on the surface (25) in a passivation step using an aqueous passivation solution. According to the invention, the passivation solution for forming the conversion coating (5) includes at least one substance that acts as a chelating agent.
摘要:
The present invention provides a method for forming a sensitive film for neutron detection, wherein the sensitive film is formed by electrophoresis coating, the liquid used for electrophoresis coating includes neutron sensitive material, electrophoresis paint and deionized water, and the neutron sensitive material is 10 B single substance, 10 B compound or mixture containing 10 B. The sensitive film for neutron detection has high detection efficiency because of the high content of 10 B. The sensitive film for neutron detection has uniform and stable film thickness, and excellent consistency. The production efficiency and the cost of the sensitive film are improved.

摘要:
A cab frame includes: a main structure (10) having an opening (30) on a part of an outer surface thereof; a rear structure (20) separably connected to the structure (10) to cover the opening (30) while projecting from the structure (10); and first and second connectors (32, 42) provided to the structure (10) and the structure (20), respectively, the first and second connectors (32, 42) connected to each other in an abutted manner when the structure (10) and the structure (20) are connected to each other. When the structure (20) is connected to the structure (10) after being turned back to front relative to the structure (10), the structure (20) is temporarily fixable to the structure (10) via the first and second connectors (32, 42). When the structure (20) is turned back to front and connected to the structure (10), the structure (20) is housed in the structure (10).
