Abstract

The invention discloses a process for preparing a ferroferric oxide magnetic layer on a stainless steel fiber surface. The process comprises the following steps: pretreatment of a stainless steel fiber, electroplating of the stainless steel fiber, treatment of the stainless steel fiber after electroplating, X-ray diffraction (XRD) analysis after electroplating the ferroferric oxide magnetic layer, observation of a surface topography by a scanning electron microscope (SEM), and magnetic vector space model (VSM) analysis, wherein the treatment of the stainless steel fiber after electroplating comprises preparation of electroplate liquid. The ferroferric oxide with good soft magnetic properties is deposited on the stainless steel fiber by adopting an electroplating technique, adjustment on the ingredients and the soft magnetic properties of the ferroferric oxide magnetic layer is achieved, so that the electrical conductivity and the magnetic property of the fiber can be remarkably improved, and the comprehensive electromagnetic properties of the fiber are good. Thus, the ferroferric oxide magnetic layer has good performances on reflection of electromagnetic waves and absorption of the electromagnetic waves, and the process is simple, convenient to operate and low in cost, and is expected to be well applied to the field of broadband electromagnetic shielding.

Description

technical field [0001] The invention belongs to the field of magnetic alloy material preparation, and in particular relates to a preparation method of a ferroferromagnetic layer on stainless steel fibers. Background technique [0002] With the development of science and technology and the electronic industry, the application of various electronic equipment is increasing day by day. Electromagnetic radiation has become a new social hazard. The electromagnetic interference caused by electromagnetic wave radiation will not only affect the normal operation of various electronic equipment, but also affect the human body. There are also health hazards. Electromagnetic radiation, also known as electromagnetic pollution, has been recognized as the fifth largest public hazard after air pollution, water pollution, noise pollution and noise pollution. And invisible, intangible, directly acting on the machine or human body, it is a serious "invisible killer". Therefore, research on th...
