The invention belongs to the technical field of metal erosion corrosion testing devices, and discloses a jet spray type sample corrosion testing device and method under a thin liquid film. The device comprises a spraying chamber, wherein an airflow nozzle, a solution atomizing nozzle and a sample bracket are arranged in the spraying chamber; the sample bracket can rotationally adjust the placement angle of a to-be-tested sample; the airflow nozzle is horizontally arranged relative to the to-be-tested sample and is externally connected with an air pump; the solution atomizing nozzle is arranged between the airflow nozzle and the sample bracket; the solution atomizing nozzle is externally connected with a solution box; the gas flow nozzle sprays gas, the gas sucks out a solution from the solution atomizing nozzle to atomize the solution, atomized liquid deposits and covers a sample to be tested to form a uniform thin liquid film, and the thickness, the retention time and the flowing condition of the thin liquid
