A method for making an improved nuclear fuel cladding tube includes reinforcing a Zr alloy tube by first winding or braiding ceramic yarn directly around the tube to form a ceramic covering, then physically bonding the ceramic covering to the tube by applying a first coating selected from the group consisting of Nb, Nb alloy, Nb oxide, Cr, Cr oxide, Cr alloy, or combinations thereof, by one of a thermal deposition process or a physical deposition process to provide structural support member for the Zr tube, and optionally applying a second coating and optionally applying a third coating by one of a thermal deposition process or a physical deposition process. If the tube softens at 800° C.-1000° C., the structural support tube will reinforce the Zr alloy tube against ballooning and bursting, thereby preventing the release of fission products to the reactor coolant.

A method for machining a crankcase includes providing a machining device. The machining device comprises a mechanical machining unit and a cooling/rinsing system, which is configured to cool and/or rinse the mechanical machining unit or a surface which is to be machined. The method also includes creating a structure in a cylinder wall of a crankcase using the mechanical machining unit. The method also includes using a fluid stream of the cooling/rinsing system to reshape at least certain regions of the structure.

The invention provides a molten Al—Si alloy corrosion resistant composite coating and a preparation method and application thereof. The composite coating layer comprises an aluminized layer and a TiO.sub.2 film layer from a surface of a substrate to the outside in sequence. The preparation method of the coating layer comprises the following steps: (step S1) making a surface treatment to an Fe-based alloy, and then aluminizing with a solid powder penetrant; (step S2) sand-blasting the aluminized Fe-based alloy; (step S3) washing and drying the Fe-based alloy which has been sand-blasted; and (step S4) depositing the TiO.sub.2 film layer on a surface of the dried aluminized Fe-based alloy by using an atom layer vapor deposition. The application of the molten Al—Si alloy corrosion resistant composite coating is used for a solar thermal power generation heat exchange tube.
