Abrasive Wear: Design of Experiment (DOE) for Determining the Wear on Crowns Used by Drilling Companies for Mineral Surveys

Abstract:

Currently companies seek performance improvement for equipment and components, and an important factor that influences performance is wear. The objective of this study was to demonstrate the applicability of a methodology that was developed using literature, field research, brainstorming, optical microscopy, statistical analysis.Wear tests for drilling crown samplesfor the production process were performed. - The crown’s chemical composition was analyzed to see if it was appropriate for the soil’s mineral lithology. Having done this, a statistical analysis was made. using Minitab 16 software, specifically applying DOE (2Kfactorial) technique. With the statistical result, a prototype was produced and subjected to a wear test for analysis of material loss compared to crowns having a better performance.Thus, the conclusion reached was that the planning process improves withthis experimental probing, which helps to identify and correct controllable factors.
