Project 4 - Measurements and characteristics to define surface condition
Objectives
- To develop in-process methods for surface assessment.
- To quantify the effectiveness of surface treatments.
- To provide basis for codes of practice.
Principal findings
- A wide range of surface treatments is necessary to prepare different materials for adhesive bonding and no one surface assessment technique wil1 find universal application. Care must be taken to match the cost of surface pre-treatment with the quality and performance of the product.
- Simple tests can be used to give information about the surface of pre-treated materials.
- It is possible to distinguish between some pretreatments with most tests.
- There is no direct relationship between the results generated and bond strength
- It is possible to categorise the test methods according to where they might be used in the manufacturing process according to the speed with which they are carried out.
