摘要

Method for detection of adulteration in markings mechanical chassis and / or engines of cars and recovery of the data of the original markings. The invention relates to a method for detection of adulteration in markings mechanical chassis and / or engines of automobiles and recovery of the data of the original marking.That includes the following steps: a) preparation of the surface.It consists in cleaning the area to be analyzed and placing a coating to contrast the color of the suspension of magnetic particles with the color of the surface to be analysed.If need; (b) mounting on the surface to be analyzed of the apparatus to induce the magnetic field; (c) application of the suspension of magnetic particles on the surface to be analyzed; and (d) determinau00e7u00e3The look of local concentration of magnetic particles and their configuration.The method can be used for forensic analysis of mechanical parts and aggregated marks of ferromagnetic material of cars with the purpose of detecting adulteration in marking and recoversR data marking original eliminated or modified.
