With a view at all times to offering the best possible response to customers’ requirements, and also in terms of constantly seeking to improve our processes, Technochim has recently purchased two new pieces of analysis equipment: a 3D microscope and an interference microscope.

They can be used, for example, to assess the condition of component surfaces (roughness) and to measure the size of defects (dimensions, depth, etc.).

Using visible light, the 3D microscope enables a micro and macroscopic analysis of the surface. The interference microscope adds to these results by enabling a more detailed analysis of the various surface defects.

Alongside the purchase of these microscopes, Technochim has extended its expertise in the use of replication.

This technique comprises applying a “leaf” of cellulose acetate to a surface. It then moulds to the surface and any defects and takes their shape.

This then enables surface defects (scratches, dents, roughness, corrosion) in the equipment (tanks, pipework, etc.) at a production site to be analysed ex situ in order to assess their magnitude and seriousness. This process thus becomes an essential aid to the decision on whether to carry out remedial work.

Replication can also be used to assess the surface parameters during the technical acceptance of a new item of equipment.
