Technological methods for improving the wear resistance of parts
Description: The main technological measures that increase the durability of machines include the following: the development of highly wear-resistant materials for various operating conditions of machines and the production of high-quality blanks from them, close in shape and size to the finished parts; the creation of technological techniques that ensure the manufacture of parts of a given accuracy and stability both in size and in physico-mechanical properties; application of quality control methods for materials, blanks and finished products according to appropriate reliability indicators; the use of hardening processing processes to obtain the required quality of the working surfaces of machine parts with high resistance to wear and breakage in various operating conditions

Goal
- students gain knowledge on various types of technologies to increase wear resistance and restoration of worn parts.
Objective
- to provide students with the basics of the theory and technology of the main methods of hardening by means of surface plastic deformation, thermal and chemical-thermal treatment.
Learning outcome: knowledge and understanding
- Modern methods for the development of technological methods increase the wear resistance of the part
- Теоретические основы различных технологий повышения износостойкости и восстановления изношенных деталей
Learning outcome: applying knowledge and understanding
- 1. Development of high-wear materials for various machine operating conditions and production of high-quality blanks from them, close in shape and size to the finished parts; 2. Development of technological techniques that ensure the manufacture of precision and stability parts, specified both in size and physical and mechanical properties; application of quality control methods for materials, blanks and finished products strength indicators; 3. The use of quenching processes to obtain the necessary quality of the working surfaces of machine parts with high wear resistance and wear resistance in various operating conditions.
- владеть методами систематического изучения научно-технической информации.
Learning outcome: formation of judgments
- 1. Choosing the optimal technological method to increase the wear resistance of the part 2. Choosing the most effective method of obtaining the part 3. Preparation of technological documentation for new technological processes
Learning outcome: communicative abilities
- Participation in the collective development of technological methods to increase the wear resistance of the part
Learning outcome: learning skills or learning abilities
- Students must distinguish between the restoration of worn parts from the basics of the theory and technology of the main methods of hardening using surface plastic deformation, thermal and chemical heat treatment
Teaching methods
Study, skills and solution of the main tasks and calculations in technological methods of increasing the wear resistance of parts
Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.
| Period | Type of task | Total |
|---|---|---|
| 1 rating | Тест-1 | 0-100 |
| 2 rating | Тест-2 | 0-100 |
| Total control | Exam | 0-100 |
The evaluating policy of learning outcomes by work type
| Type of task | 90-100 | 70-89 | 50-69 | 0-49 |
|---|---|---|---|---|
| Excellent | Good | Satisfactory | Unsatisfactory | |
| The results of the current control and final certification form a rating assessment of the student's work. The distribution of points for certain types of work in the process of mastering the discipline is carried out in accordance with the schedule of assignments in the discipline. The control system can combine written and oral, group and individual forms. | Completing tasks Independent work of the student for 100-90% | Completing tasks Independent work of the student for 89-70% | Completing tasks Independent work of the student for 69-Completing tasks Independent work of the student for 100-90%% | Completing tasks Independent work of the student for 100-90% |
Evaluation form
The student's final grade in the course is calculated on a 100 point grading scale, it includes:
- 40% of the examination result;
- 60% of current control result.
The final grade is calculated by the formula:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
Final alphabetical grade and its equivalent in points:
The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
| Alphabetical grade | Numerical value | Points (%) | Traditional grade |
|---|---|---|---|
| A | 4.0 | 95-100 | Excellent |
| A- | 3.67 | 90-94 | |
| B+ | 3.33 | 85-89 | Good |
| B | 3.0 | 80-84 | |
| B- | 2.67 | 75-79 | |
| C+ | 2.33 | 70-74 | |
| C | 2.0 | 65-69 | Satisfactory |
| C- | 1.67 | 60-64 | |
| D+ | 1.33 | 55-59 | |
| D | 1.0 | 50-54 | |
| FX | 0.5 | 25-49 | Unsatisfactory |
| F | 0 | 0-24 |
