High-flux optimization method for nano ceramic phase in ceramic reinforced alloy

The invention discloses a high-flux optimization method for a nano ceramic phase in a ceramic reinforced alloy. The high-flux optimization method comprises the following steps that S1, stainless steel substrate powder is mechanically mixed with nano powder with different components and proportions to prepare multiple kinds of mixed powder; S2, a laser cladding method is adopted to print the multiple kinds of mixed powder into plate-shaped single-arm samples according to component gradient partitions; S3, the single-arm samples are cut into wedge-shaped structures, single-pass flat rolling is carried out through a common hot rolling mill after high-temperature heat preservation treatment, and rolled plates with the same thickness under the condition of different deformation amounts are obtained; and S4, the strengthening degrees of different component parts of the samples at different deformation amounts are evaluated by adopting a grid dot-by-dot printing hardness method.
