Aiming at the weakness of traditional static forward feedback neural network in dynamic performance,the dual part-return Elman neural network is put forward.

The method of orthogonal polynomial regression was used for regression modeling,and then the regression equations and regression coefficients were tested for significance.

Composite powder was optimized by orthogonal design and orthogonal polynomial regression using surface hardness of surfacing layer as testing index, and wear experiments of surfa cing layer with different compositions were carried out on the type MM-200 wear test equipment.
