The deposit acts as an anode with respect to the basis metal when oxidation occurs. It protects the base metal.
Zinc plated on steel is an example.
SOCIETY OF AUTOMOTIVE ENGINEERS
The common name for ammonium chloride.

by the solution causing it to 'drop-out'.

A scatter diagram is a visual tool for showing the relationship between two variables.
It shows clearly if there is a relationship, or correlation, between the two variables:
POSITIVE CORRELATION - as x increases, so does y; NEGATIVE CORRELATION -
as x increases, y decreases; NO CORRELATION - one quantity has no particular
relation to the other. It provides the verification of a potential root cause.

SEVEN BASIC TOOLS of QC
The major use of QC tools is to provide objectivity and clarity. The tools separate
opinions from data-based logic, thereby allowing anyone to 'speak with facts.'
The SEVEN TOOLS of QC are : CHECKSHEET, PARETO CHART, ISHIKAWA or
FISHBONE DIAGRAM, GRAPH, HISTOGRAM, SCATTER DIAGRAM, and CONTROL CHARTS.

A method of coating steel with a thin adherent film of zinc, by sintering zinc powder.
SUBSTANCE HAZARD INDEX
A form of burnishing which uses no abrasive or chemicals. Usually burrs are peened against each other to improve luster.

A statistical way of measuring quality, six-sigma is equivalent to 3.4
defects per million units of output-a virtually defect-free level of performance.
The ambitious, company wide goal of 'SIX-SIGMA QUALITY' has been adopted
by Motorola, a 1988 Baldridge Award winner.
The common name for calcium hydroxide.

SOLID FILM COATING
A process in which the parts (bearings) are coated with a resin-bonded lubricant like molybdenum disulfide, graphite or polytetra-fluoroethylene.
Any foreign material on the surface of base metal such as grease oil oxide
dust fingerprints smut paint flux or other unwanted film.
STANDARD OPERATING PROCEDURE
STATISICAL PROCESS CONTROL
Based on the principle that no two units of output of a process are likely to
have the exact same specifications SPC involves the mathematical determination
of acceptable limits of variation. Graphs are used by workers to plot
output variables and visually determine when a process is 'IN' or 'out of' control.
SPILL PREVENTION CONTROL AND COUNTERMEASURE PLAN
The conformance boundary for the individual characteristics for a manufactured item.
SOCIETY OF PLASTIC ENGINEERS
An 'abnormal' source of variation that does not arise from the production process
itself but which is extraneous and unpredictable.
Specification limits are determined by the customers' valid requirements regardless
of what the process is capable of achieving.

STATISCAL QUALITY CONTROL
A relatively early development in the evolution of the quality discipline, SQC
relies on statistical concepts and tools ( e.g., sampling techniques ) to control
production quality. SQC techniques are used in TOTAL QUALITY MANAGEMENT,
although the emphasis in TQM is on 'building quality in,' rather than error detection.

The STANDARD DEVIATION is a measure of how tightly the data points cluster
about the mean ( average ). It is represented by Sigma ( o-). The Standard
Deviation is far less sensitive to the addition of another data point or the changing
of a data point; therefore, it is a more reliable MEASURE OF THE VARIABILITY of a process.
A fine salt-and-pepper like nickel deposit, caused by codeposition of metallic contaminant such as iron, aluminum or calcium.

Stratification is a technique used for breaking down the whole ( total area of concern )
into smaller, related subgroups. Stratification of information specifies the data and enables
someone to do a more precise analysis of it. It is a useful tool for verifying root cause.
An ambitious usually long-term quality goal that requires extraordinary effort
innovation and planning to achieve.
Thin layer of nickel or copper over a clean active raw base metal plated from a
corrosive low-metal content bath; used on stainless steel.
An analytical process which measures the applied voltage versus anodic stripping. It consists of stripping the species
electrochemically until there is a change in voltage.
Any exposed surface of the raw parts to be plated; ( also called 'base' 'base metal' or 'raw part' ).
A test of a hypothesis using small sample inferences for a population.
