การพัฒนากระบวนการอบผนึกชิ้นงานความแข็งสูงพิเศษเพื่อเพิ่มประสิทธิภาพ การต้านทานการสึกหรอตามแนวทางการจัดการวัสดุเพื่อความยั่งยืน
This study aims to development of production process of hard metal by tungsten carbide powder with the particle sized of 0.1 - 0.35 µm. This carbide powder were made of recycling cemented carbide tool scraps so it is mixed with Ta = 2.82 % Mo = 0.45 % Nb = 1.22 % Ti = 4.56 % Zr = 0.37 % The shape of the carbide powder are roughly round due to ball milling for 300 hours. It was mixing cobalt 10 % and Paraffin wax 2 % which is found the work piece that running through the process of sintering with a temperature of 1400 °c and 1430 °c have the hardness of 1368.5 and 1346.3 HV respectively. In one hour of holding time process the work piece with 1430 °c of the sintering causes less wear. After the test of turning operation it can be concluded that the tungsten carbide cutting tool provides the equivalent quality as a standard cutting tool.
Factors affecting the personal financial management of personal in Rajamangala University of Technology in Bangkok Area
The purpose of this study was to study factors affecting the personal financial management of personal in Rajamangala University of Technology in Bangkok area. These factors were divided into 4 factors; first of them was personal factor: age academic position and salary second of them was family factor: family responsibility third of them was environmental factor in the workplace: imitation to their peer groups in office and fourth of them was factor of social environment: the influence of the media. The samples in this research were 334 personals. The study participates selected by stratified random sampling. The Instruments used in this study were the interview and rating scale questionnaire 5 levels of 16 items discrimination since 0.31 to 0.69 and alpha coefficient of 0.86. Percentage mean standard deviation χ2 - test and stepwise multiple regression analysis were statistical method to analyze data. The results were as follows: 1. The personal factor: age academic position and salary no related to the personal financial management of personal in Rajamangala University of Technology in Bangkok area. 2. The factors related to the personal financial management of personal in Rajamangala University of Technology in Bangkok area statistically significant at the level of significant 0.01 in the order correlation coefficients (rxy) descending as follows: family factor (0.556) environmental factor in the workplace (0.295) and factor of social environment (0.120) 3. The factors which could predict the personal financial management of personal in Rajamangala University of Technology in Bangkok area at the 0.01 level significant: family factor (X1) and factor of social environment (X3) with the multiple correlation coefficients (R) of 0.627 and coefficient of determination (R2) of 0.393. The predicted equation of affected the personal financial management of personal in Rajamangala University of Technology in Bangkok area at 0.01 level were as follows 3.1 In terms of raw scores were : yˆ = 0.776 + 0.700x1+0.085x3 3.2 In terms of standard scores were : Y = 0.553x1+0.289x3
