Abstract: The present invention relates to the field of sheet hot stamping and sheet metal parts manufacturing, and provides a hot bath forming process for high-corrosion-resistance easy-to-weld hot-pressed parts. The process comprises the following steps: S1, heating a coated hot-formed steel sheet material in a heating furnace, and heating to a completely austenitized state; S2, transferring the heated coated hot-formed steel sheet material into a boiling water tank, immersing the heated coated hot-formed steel sheet material into boiling water, and cleaning an oxide layer; S3, forming the coated hot-formed steel sheet material under the combined action of boiling water and an upper mold and a lower mold, and performing pressure maintaining and quenching to obtain parts; and S4, taking out the parts for air blowing or drying the parts in a drying furnace to remove water in the coating of the parts.

Abstract: A measurement system for detecting deep-hole surface topography based on low-coherence interferometry (LCI), can include a detection part and an autocollimation system. The detection part includes a white light interferometric system, which specifically includes a 1550 nm amplified spontaneous emission (ASE) broadband light source, a first reflector, a first beam splitting prism, a second reflector, and a reference reflector that are arranged in sequence, where a to-be-measured deep-hole and a near-infrared camera are respectively arranged at two sides of the first beam splitting prism, and a conical prism is disposed inside the to-be-measured deep-hole. The autocollimation system is disposed between the to-be-measured deep-hole and the first beam-splitting prism. The autocollimation system includes a 630 nm light source, a dichroic prism, a second beam-splitting prism, a third reflector, and a quadrant detector that are arranged in sequence.
