Abstract
This work presents ANOVA and Tukey’s statistic tests that were carried out in Knoop microhardness results of boron carbide sintered samples. Three samples, A, B and C, of different processing conditions were tested and statistical analysis showed that microhardness results are strongly influenced by porosity and chemical composition, mainly due to presence of C(2H) and WB2.5 contaminant phases. Those phases promoted higher densification in A and B samples and it was found that A ≈ B > C is the relation between the microhardness results of the samples, while A ≈ B < C is the porosity ratio of the samples. Furthermore, this work aims to apply a statistical tool to evaluate the microhardness results performed on advanced ceramics and, using these results, to control parameters in the sintering process, showing that a deeper statistical analysis is necessary for the interpretation and validation of the results merit.
期刊介绍：
The Journal of Applied Research and Technology (JART) is a bimonthly open access journal that publishes papers on innovative applications, development of new technologies and efficient solutions in engineering, computing and scientific research. JART publishes manuscripts describing original research, with significant results based on experimental, theoretical and numerical work.
The journal does not charge for submission, processing, publication of manuscripts or for color reproduction of photographs.
JART classifies research into the following main fields:
-Material Science:
Biomaterials, carbon, ceramics, composite, metals, polymers, thin films, functional materials and semiconductors.
-Computer Science:
Computer graphics and visualization, programming, human-computer interaction, neural networks, image processing and software engineering.
-Industrial Engineering:
Operations research, systems engineering, management science, complex systems and cybernetics applications and information technologies
-Electronic Engineering:
Solid-state physics, radio engineering, telecommunications, control systems, signal processing, power electronics, electronic devices and circuits and automation.
-Instrumentation engineering and science:
Measurement devices (pressure, temperature, flow, voltage, frequency etc.), precision engineering, medical devices, instrumentation for education (devices and software), sensor technology, mechatronics and robotics.
