Solid Gaseous State Boronization

In solid gaseous state boronization,a special solid boronizing agent isused.During the process of heating and heat preserving,the boronizingatmosphere is formed as being engaged in the acute and complex chemicalreaction.As a result,the boronization is realized without the contactbetween workpiece and boronizing agent.For steel materials,a singlephase Fe_2B structure with good properties will be got.By this method,the defects of solid,liquid and gas boronization were overcome,and themethod has the advantages of gas boronization.The method of solid gaseous state boronization has obtained patentof the National Patent Office.A special dectrie furnace for solid gaseousstate boronization is produced by Nanjing Sheshan Electric FurnaceFactory.
