英文摘要：

The high silicon steel is a kind of soft magnetic alloy with excellent magnetic properties. But its room-temperature brittleness seriously affects the thermal processing performance, and the brittleness at room temperature and low processing property of high silicon steel can be avoided by deposition diffusion method. Some kinds of deposition diffusion processes for preparing high silicon steel were illustrated, such as electrical phoretic deposition, electron beam physical vapor deposition, laser cladding, hot-dip and molten salt electro-deposition. The advantages,disadvantages and research statuses of various methods were summarized from the reaction principle of deposition, process conditions and properties of silicon steel, and the developing direction in the future was put forward.
