Abstract: The marine corrosion of metal materials is a complex chemical process which is affected by multiple factors that are nonlinear interconnected.
Because the available sample data of the marine corrosion of metal materials are both small and high dimensional, it is important to study on a method of data processing and model building to determine a possible critical point in metal material corrosion, and so to take precautions to avoid future loss for materials failure.
For such small sample data as the marine corrosion of metal materials, the information contained is limited.
Firstly, use Grey relational analysis to figure out the main factors in the marine environment that affect the corrosion rate of metal materials, then use the PLS to establish a model for the corrosion rate and depth of metal materials.

Numerical Simulation of the Temperature Field in Multi-layer Powder-feeding Laser Cladding Forming Zhang Jun, Song Jian Li, Li Yong Tang,Chen Fei School of Materials Science and Engineering, Taiyuan University of Science and Technology, Taiyuan, 030024, China Keywords：Laser Cladding Forming; Numerically Simulation; Temperature Field; Element Birth and Death; Temperature Gradient Abstract: The numerically simulation of temperature field was carried out by the ANSYS software in multi-layer powder-feeding laser cladding forming. 3-D finite element model was found, which nonlinear characteristics of the material thermal properties and the boundary conditions of the convective transfer heat was considered; The process of powder falling into the substrate and cladding element growing was accomplished by “Element Birth and Death technology” in the process of numerical simulation.
Therefore, this paper adopts moving of the Gaussian heat source model as laser heat source model, using the “Element Birth and Death technology” to achieve powder- feeding process, using the ANSYS finite element software to simulate the temperature field of multi-layer powder-feeding laser cladding forming, it has a important significance to the choice of technological parameters in the process of laser cladding forming. 2, Building finite element model 2.1 Cladding technological parameters and the selection of materials The substrate material selects as Q235 steel, the cladding material selects as 316L stainless steel.
