Numerical Computing for Analysis of the Characteristics of Ceramic PSZ with MGO Additives, Matlab-based CaO

Introduction

In the field of materials science, the development of advanced ceramics has been a significant area of research, with a focus on creating materials that possess unique properties such as high toughness, resistance to high temperatures, and excellent mechanical strength. One such material is Partially Stabilized Zirconia (PSZ), which has been widely used in various applications including cutting tools, biokeramics, and refractory materials. In this study, we aim to analyze the characteristics of PSZ ceramics with MGO and CAO additives using numerical computing methods based on Matlab programming version 7.0.1. 24704 (R14) released on September 13, 2004.

Analysis of Ceramic Characteristics

The analysis of ceramic characteristics is a crucial step in understanding the behavior of PSZ ceramics under various conditions. In this study, we have analyzed several important parameters, including:

Density

Density is a fundamental property of materials that describes the mass per unit volume of a material. The computing results show that the density of CA-PSZ with 8.64% CAO ranges from 3,9289-5,7735 x 10³ kg/m³, while MG-PSZ with 12% MGO has a density between 4,3810-5,8732 x 10³ Kg/m³. High density indicates a more dense material, which is generally stronger and more resistant to deformation.

Porosity

Porosity is a measure of the percentage of empty space in a ceramic material. For CA-PSZ, the porosity value was found between 9,3434-27,3391%, while for MG-PSZ between 7,4747-20,0420%. Low porosity is usually directly proportional to the mechanical strength of ceramic, indicating that materials with low porosity are more resistant to deformation and cracking.

Violence (GPA)

Violence is a measure of a material's resistance to deformation, expressed in GPA units. CA-PSZ shows the value of violence between 8,2393-27,3388 GPA, while MG-PSZ ranges from 5,0377-29,8253 GPA. High violence indicates that the material can survive in extreme conditions, making it suitable for applications that require high mechanical strength.

Toughness (Fracture Toughness)

Toughness is a measure of a material's ability to withstand cracks, expressed in MPA M¹/² units. The analysis showed the toughness for CA-PSZ was 1,8883-2,4944 MPA M¹/², while MG-PSZ had a toughness between 1,4064-2,5355 MPA M¹/². High toughness indicates that the material can withstand significant stress without cracking or breaking.

Broken Power

The value of the broken power for Ca-PSZ ranges from 360,363-648,844 MPA, and for MG-PSZ between 381,1607-712,7880 MPA. This parameter is crucial in understanding the material's ability to withstand impact and deformation.

Coefficient of Thermal Expansion

The Coefficient of Thermal Expansion (CTE) is a measure of a material's ability to change dimensions when exposed to temperature changes. The results show that the thermal expansion coefficient for CA-PSZ ranges from 16.5-10.3 x 10⁻⁶ ° C⁻¹ and for MG-PSZ between 17.1-12.3 x 10⁻⁶ ° C⁻¹. This parameter is essential in understanding the material's behavior under thermal stress.

Through numerical computing analysis, it can be concluded that the two types of PSZ ceramics with CAO and MGO additives show characteristics that are useful for applications in various industrial fields. High density, adequate violence, and good toughness make it ideal for use in cutting devices and materials that require high temperature resistance.
