The work provi.es the results of the one-step form.ti.n of boron-contai.i.g coati.gs on an m.–m.–Ce alloy by plasm. electrolyti. oxi.ati.n. The results of studi.s of the com.osi.i.n, structure and m.rphology of heteroxi.e coati.gs are presented. i. was establi.hed that the boron i. contai.ed i. the coati.g m.i.ly i. the form.of B or B_(2)O_(3). The i.troducti.n of B changes the color of coati.gs, and also helps to i.crease thei. porosi.y.
