Grading Plan:
20% homework (~4 assignments), 20% midterm (1), 25% final (1).
35% lab (5 lab write-ups and presentation; no formal lab reports).
Professional Component Content:
Engineering Science: 2.5 credits or 83%.
Engineering Design: 0.5 credits or 17%.
Design Component Content:
In lectures students learn the principles of design for corrosion resistance. In lab exercises, students must understand the fundamentals of experimental design to isolate variables and determine their influence on material response
Relation to Program Objectives:
1. This course covers the fundamental concepts in corrosion science and engineering.
2. Students have the opportunity to exercise fundamental concepts in structured laboratory exercises that parallel lecture material.
3. Students have the opportunity to understand the relationships between processing, resulting microstructure, and corrosion susceptibility of metals and alloys.
4. This course prepares students for graduate research and employment in the area of materials design, engineering design, and corrosion science and engineering.
Academic Integrity, Academic Misconduct
Academic misconduct may be found in any action that tends to distort the accurate assessment of any student’s individual accomplishments that are evaluated for the purpose of grading or conferring academic credit. Note that a student may be guilty of academic misconduct, for example, by cheating, collaborating, plagiarizing, or by allowing another student to cheat, collaborate, or plagiarize. Note also that the distortion applies, for example, to exams, homework assignments, and laboratory work. To the extent that any class activity (for example: attendance or participation) is used for evaluation for the purpose of grading or conferring academic credit, falsifying or distorting such activity, or permitting another student to falsify or distort such activity, represents academic misconduct.
Additional guidance about what represents academic integrity and misconduct, and related university-wide policies and procedures are available at the following locations:
http://oaa.osu.edu/coam/faq.html
http://oaa.osu.edu/coam/ten-suggestions.html
Course-specific exceptions or amplifications to the departmental and university statements outlined above will be provided by the faculty instructor in writing, preferably as part of the course syllabus.
Note: Students should not request nor accept guidance on these matters from a teaching assistant, fellow student, or anyone other than the faculty instructor of record for this course.
Disabilities Statement
Any student who feels s/he may need an accommodation based on the impact of a disability should contact the Office for Disability Services at 614-292-3307 in room 150 Pomerene Hall to coordinate reasonable accommodations for students with documented disabilities. (URL: http://www.ods.ohio-state.edu/)
Advice on such matters is also available from the MSE department’s undergraduate adviser (1xx-6xx courses) and graduate coordinator (7xx-9xx courses) whose offices may be found in room 477 Watts Hall.
