Other properties of an abrasive have an effect on the resulting substrate also, these being.A. Size of the particlesB. Hardness of the materialC. Density of the materialD. Shape of the particleE. Velocity of abrasiveF. Angle of impingementG. Time & distance For example steel has a density of approximately 7.6 gm/cc and copper slag, approximately 4.2 gm/ccIf one particle of each material, of identical size, hit a steel substrate, then it would be logical to say that the steel would impinge further into the substrate, resulting in a deeper trough. A spherical particle would not impinge as deeply because the large smooth surface area would use its energy up in preening or work hardening the surface rather than cutting into it. So a shot blasted surface is different...

In the context of this course we are considering the following: -a) SandIt is not permitted to use sand.  SI 1657 states that any mineral used as an abrasive must release less than 1% free silica on impact.  (Silica causes preumonicosis or silicosis).  COSHH REGS does not allow the use of sand containing silica for dry blasting.  Sand itself is perfectly safe, but shattering on impact releases silica which can be inhaled. The amount of copper in the structure is extremely minute. b) Copper Slag Copper Slag 1. Minerals melted with the copper,2. Liquefies and forms a protective cover over the molten...

SURFACE PREPARATION METHODS & STANDARDSIf paint is applied over the corrosion reactions, and other contaminants,  1. The poor adhesion of the coating and thus the coatings life would be far from satisfactory.  2. A good surface preparation grade (degree of cleanliness) along with a suitable surface profile can give 10 years life from a typical four-coat paint system.  The same system applied over a substrate with little or no profile and contaminant remaining might give four to six years, or even less.Surface PreparationInvolves removing these contaminants, and in some instances increasing the area available for adhesion by roughening up the substrate.Therefore two factors need to be considered when inspecting a surface preparation.1.        ...

BGAS Painting Study Material Chapter 1 Corrosion

Corrosion can be generally defined as;” Degradation of a metal (material) by chemical or Electro-chemical means. It is obvious that two mechanisms are involved, Firstly an Electrical Circuit and secondly a Chemical Reaction. Electrical CircuitIn corrosion circuit the current is always D.C. (Direct Current). For corrosion circuit to exist three things are needed: Anode, Cathode and Electrolyte.1. An AnodeIs a positively charged area?  (It becomes positively charged because the atoms release two     electrons), the iron atom has 26 of each,...
