Morphology and Chemical Composition of the Titanium Alloy Surface at the Initial Stage of Grinding with a Cubic Boron Nitride Wheel

The article summarizes the results of the of the titanium alloy surface morphology and chemical composition study after grinding with a wheel of cubic boron nitride on a ceramic bond. The titanium alloy was treated using the method of cut-in grinding in the finishing mode using a synthetic water-soluble lubricant-cooling liquid that does not contain mineral oil. The research was carried out using the FEI Versa 3D LoVac electron microscope. Digital photos of the titanium alloy surface at different magnifications are given. Individual objects’ morphology allows us to identify them as wear products of abrasive tools. The chemical composition of the selected objects was studied by local x-ray spectral analysis. CBN crystals are partially or completely pressed into the treated surface and covered with a layer of the treated material. On the surface of CBN crystals, there are chemical elements that are part of the abrasive tool bond.

The article summarizes the results of microscopic and x-ray spectral studies of objects embedded in the surface layer of a nickel alloy after grinding with a wheel of cubic boron nitride (CBN) on a ceramic bond. In the introduction, the authors analyzes the results of research on the use of CBN as an abrasive material. Unlike silicon carbide wheels, CBN tools are a more complex and multi-component structure, which has a significant impact on the self-sharpening of the abrasive tool and the transfer of material. The purpose of this article is to detect and identify the wear products of a CBN grinding wheel on the treated surface of a nickel alloy. As a result of studying the morphology of the alloy surface after grinding with CBN wheels, foreign objects embedded in the metal were detected with a scanning two-beam electron microscope. The chemical composition of the objects was studied by x-ray spectral microanalysis. Based on the obtained spectrograms, the objects were divided into three groups, including peaks of x-ray characteristic radiation: boron and nitrogen characteristic of CBN grains; aluminum and oxygen characteristic of corundum; oxygen, silicon, aluminum, and some elements characteristic of a ceramic bond. Tables of the chemical composition of the studied objects are provided. Conclusions. The transfer of CBN grinding whee wear products from to the treated surface is experimentally proved.

The results of the study of the morphology and chemical composition of the surface of 10895 electrical steel obtained during the first period of grinding with a wheel made of cubic boron nitride on a ceramic bond are presented. It is shown that in comparison with grinding in the same conditions of titanium alloy, the intensity of the adhesive interaction of the abrasive tool with the processed material is significantly less. Despite a significant decrease in the intensity of adhesive interaction with the abrasive material, wear products of the grinding wheel were found on the treated surface of the steel. The results of morphological and electron microprobe analyses allow to identify the products of wear, as the crystals of cubic boron nitride.

In this paper, grinding forces of titanium alloy Ti-6Al-4V are measured during creep feed grinding with brazed cubic boron nitride (CBN) wheels. The effects of process parameters on grinding force, force ratio and specific grinding energy are investigated in detail. The grinding force is low and force ratio is about 1.5, and the specific grinding energy of titanium alloys Ti-6Al-4V is about 65J/mm3. Also, CBN wheels brazed with composite filler of Ag-Cu-Ti and 0.5wt.% lanthanum show better grinding performance than the counterpart brazed with Ag-Cu-Ti filler in this investigation.
